CIO Playbook: Selecting the Right Microsoft 365 Enterprise Plan (2025 Edition)
Introduction
Chief Information Officers (CIOs) face a complex landscape when choosing a Microsoft 365 enterprise plan. This playbook aims to provide a neutral, detailed guide for selecting the optimal Microsoft 365 plan for your organization.
We will cover the major enterprise plans (E1, E3, E5), as well as the Business plans relevant to larger organizations, including their pricing, features, and available add-ons such as Microsoft Copilot, Defender, and Viva.
All recommendations emphasize the importance of engaging independent licensing experts for clarity and fairness.
Key Takeaways:
- Microsoft 365 plans vary significantly in capabilities and cost, so it is crucial to align them with your organization’s specific needs.
- Enterprise plans (E-series) serve information workers with full productivity suites, while Frontline plans (F-series) target field or customer-facing staff with lighter tools.
- Mix-and-match licensing enables you to assign plans to various user groups, optimizing value.
- Consider regulatory compliance, security needs, workforce type, and budget constraints when evaluating plans.
- Independent licensing advisors (not just vendors) should be consulted to navigate complexities, optimize costs, and ensure compliance.
Overview of Microsoft 365 Plans and Their Distinctions
Microsoft 365 has multiple tiers tailored to organization size and worker type. Understanding how Enterprise (E-level), Frontline (F-level), and Business plans differ is important.
Below is an overview of each major plan as of 2025, along with core features and pricing.
Enterprise Plans (E1, E3, E5)
Enterprise “E” plans are designed for organizations with over 300 users or complex requirements. These plans include the full Office 365 cloud services suite, and the Microsoft 365 versions also bundle Windows Enterprise OS and advanced security (EMS) features.
Key differences are in the availability of desktop apps and the depth of security/compliance tools:
- Microsoft 365 E1: Entry-level enterprise suite. Provides core cloud services but no desktop Office apps. Users receive web and mobile versions of Word, Excel, PowerPoint, Outlook, Teams, business email (with a 50 GB mailbox), and 1 TB of OneDrive cloud storage. Basic collaboration via SharePoint and Teams is included. Security and compliance features are limited to baseline capabilities (e.g., Exchange Online Protection for email). Price: Approximately $10 per user/month (annual commitment). This low-cost plan suits organizations that need email and web Office access for multiple users without heavy content creation requirements. However, the lack of desktop apps means it’s not ideal for power users who require full offline functionality.
- Microsoft 365 E3: Standard enterprise plan. Includes full Office desktop applications on up to 5 PCs/Macs per user and web and mobile apps. Provides enhanced services: Exchange Online Plan 2 (100 GB email + unlimited archive), SharePoint, Teams with meeting and collaboration features, and 1 TB OneDrive (expandable for large orgs). Importantly, E3 adds advanced enterprise security & device management: Azure Active Directory Premium P1 for identity management, Microsoft Intune for device/application management, and information protection (e.g. data loss prevention, BitLocker management). Windows 10/11 Enterprise OS upgrade rights are included, allowing use of Windows Enterprise on licensed devices. Compliance features, including legal hold and basic eDiscovery, are provided. Price: Approximately $36 per user/month. E3 is often the best fit for most enterprises, balancing comprehensive productivity tools with robust (but not cutting-edge) security/compliance. It addresses the typical needs of organizations that require desktop Office and moderate security.
- Microsoft 365 E5: Top-tier enterprise plan. Includes everything in E3 plus a full suite of advanced security, compliance, telephony, and analytics. E5 brings Microsoft’s highest-end features: Azure AD Premium P2 (with Privileged Identity Management and Identity Protection), Microsoft Defender for Endpoint, Defender for Office 365 Plan 2 (advanced threat protection for email and collaboration), Defender for Identity (on-prem AD threat detection), and Cloud App Security – essentially the full EMS E5 security suite is included. Compliance and information governance are enhanced via Microsoft Purview (advanced eDiscovery, Audit, Records Management, and Insider Risk management tools). Power BI Pro is included for all users (enterprise business intelligence) for analytics. In communications, E5 includes Phone System and Audio Conferencing capabilities – enabling Teams telephony (though calling plans or Direct Routing minutes are extra) and dial-in audio conferencing for meetings. Price: Approximately $57 per ser/month. E5 is suited for large organizations in highly regulated or security-sensitive industries (finance, healthcare, government) that need state-of-the-art protections, or those wanting built-in analytics and calling capabilities. The cost is roughly 50% higher than E3, so businesses must ensure they need the added features to justify this tier.
Note: Microsoft also offers Office 365 E1, E3, and E5 plans, which include the Office apps and cloud services but exclude the Windows OS and certain security components.
This playbook focuses on the full Microsoft 365 versions of E3/E5 (which bundle the OS and EMS security suite). If your organization already covers Windows licensing separately or through upgrades, you may choose Office 365 E3/E5 instead; however, many enterprises prefer the integrated Microsoft 365 bundle for its simplicity.
Also, as of 2024, Microsoft introduced versions of the Enterprise plans “without Teams” (reflecting regulatory unbundling in some regions).
These have slightly lower base prices but require a separate $ 5 monthly Teams Enterprise license if you need Teams functionality, often resulting in a higher combined cost. For most CIOs, the regular plans (with Teams included) remain the standard choice for an all-in-one suite.

Frontline Worker Plans (F1, F3)
Frontline “F” plans are optimized for frontline employees who primarily work in the field, on the shop floor, or in customer service roles (e.g., retail associates, factory workers, nurses, etc.).
These users may not need full desktop apps or may share devices, so F plans provide essential communication and cloud services at a lower price point:
- Microsoft 365 F1: Kiosk/Essentials plan for the frontline. Offers the basics for communication: Microsoft Teams (chat, meetings, limited channels), SharePoint (for intranet access), Viva Engage (Yammer Communities for company-wide communications), and web-based viewing of Office files. F1 users get Exchange Online Kiosk (a 2 GB lightweight mailbox with Outlook on the web only, no Outlook desktop client) – sufficient for calendar and occasional email needs, but not a full Exchange license. OneDrive storage is very limited (e.g., 2 GB). No Office apps are included (not even web editing for Word/Excel) – F1 is primarily for messaging and intranet access. Basic security is in place for these cloud services, but devices are often shared or locked-down kiosks. Price: $2.25 per user/month (with an annual commitment). This plan is suitable for employees who need to access email, calendars, or receive company updates on shared terminals or personal mobile devices, such as shift workers or retail staff. It’s extremely limited for content creation or independent work.
- Microsoft 365 F3: Full-featured frontline plan. This plan is a significant step up, including web and mobile versions of Office apps (Word, Excel, PowerPoint) for productivity on the go (still no desktop Office installation rights, however). Users get a 2 GB mailbox with web/Outlook mobile access and 2 GB OneDrive storage – these caps align with frontline usage patterns (heavy email or storage needs would warrant an E plan). F3 also comes with Microsoft Teams (for chat/meetings) and SharePoint, similar to F1 but with more capability to create/edit content via web Office. Notably, Microsoft 365 F3 includes a license for Windows Enterprise E3 and basic device management rights, allowing users to log into a Windows Enterprise device (ideal for shared workstation scenarios or when frontline users have company-issued tablets). It also features some security enhancements, including Microsoft Defender (endpoint protection optimized for lightweight devices) and Credential Guard, which helps secure identity on shared devices. Price: $8 per user/month. F3 is ideal when frontline personnel must participate in data entry, view/edit documents, or use Microsoft 365 apps on tablets/phones. However, you still want to control costs and don’t require full desktop Office installations. It strikes a balance by providing frontline workers with access to the cloud ecosystem and Windows, without the full expense of an E3 license.
Important: F-plan licenses are often applied to large enterprises with many users (e.g., thousands of retail workers), so their lower cost can save significantly compared to assigning E licenses to users who would underutilize them.
However, remember the storage/mailbox limitations – organizations must plan how frontline staff will operate within those constraints (e.g., using shared mailboxes or Teams for communication instead of individual large mailboxes).
Business Plans (for SMB, up to 300 users)
In addition to E and F plans, Microsoft offers Business plans (Business Basic, Business Standard, Business Premium, and others,) which are capped at 300 users per plan.
These plans are typically marketed to small and mid-sized businesses. Still, larger organizations (enterprise tenants) might consider them for certain scenarios (for example, a subsidiary or a pilot group) as long as they stay within seat limits.
Each Business plan provides a bundle of Office 365 services with some differences in included features and security:
- Microsoft 365 Business Basic: Cloud services only, similar to E1. Includes Exchange email (50 GB mailbox), Teams, SharePoint, and OneDrive (1 TB), with web and mobile app access only for Office apps (no desktop apps). Price: $6 per user/month (annual). This is a low-cost option for small organizations or users who only need email and online Office. Still, it’s rarely used in larger enterprises except perhaps for interns or certain contractors due to the 300-user cap and limited functionality.
- Microsoft 365 Business Standard: Adds desktop Office apps to what Basic offers. Users can install Word, Excel, PowerPoint, Outlook, etc., on their devices (up to 5 devices per user), just like an E3 user, and they get 1 TB of OneDrive and 50 GB of email. However, Business Standard does not include advanced security or device management beyond the basics (no Azure AD Premium or Intune – it relies on standard security in Office 365). Price: $12.50 per user/month. This plan mirrors many Office 365 E3 capabilities but is only for <300 seats and lacks enterprise-level security/compliance tools.
- Microsoft 365 Business Premium: The most comprehensive SMB plan, combining Business Standard’s full Office suite with advanced security and device management (in a way, it’s like a mini-E5 tailored to SMB). Business Premium includes Azure AD Premium P1, Microsoft Intune for device management, and Microsoft Defender for Business, bringing endpoint protection and threat detection capabilities. It also offers conditional access, built-in MFA enforcement, and other security features crucial for organizations that can’t afford separate security solutions. However, Business Premium still offers a 50 GB mailbox (with no unlimited archive), 1 TB OneDrive. It lacks some advanced compliance/analytics features found in E5 (e.g., no Power BI, no advanced eDiscovery by default). Price: $22 per user/month. Business Premium is extremely popular among organizations with up to 300 users because it offers a cost-effective package: essentially, Office 365 E3 plus many E5 Security features, at a lower price than an Enterprise E3 license. For enterprises, you cannot assign Business Premium to more than 300 users within a single tenant; it’s an option if you have a smaller division or are in the mid-market size range. Remember that if you grow beyond 300, you’ll be pushed to migrate to E plans.
Business vs. Enterprise:
Microsoft officially reserves Business plans for up to 300 users (and technically enforces a 300-license limit per plan type).
Large organizations with more than 300 employees are advised to use Enterprise plans, though combinations are possible (e.g., 300 users on Business Premium and the rest on E3).
Enterprise plans offer higher capacity and more robust compliance options than Business plans. For example, Exchange Online in E3/E5 can support larger mailboxes and archiving. OneDrive storage can be extended beyond 1 TB for E3/E5 users.
Enterprise plans include features like Teams Phone and Power BI integration that Business plans do not.
Moreover, enterprise support, SLAs, and add-on availability might be better with E plans. Enterprise plans are typically the best option if your organization has 300 or more users or requires advanced functionality.
Business Premium can be viewed as a subset of E3 and some E5 security, making it ideal for smaller environments, but not scalable indefinitely.
Add-Ons: Extending Your Plan’s Capabilities
Beyond the base plans, Microsoft offers a range of add-on licenses that CIOs can use to tailor capabilities.
These can be crucial in selecting a plan strategy – sometimes it’s more cost-effective to choose a lower plan and add a specific feature, rather than upgrading every user to a higher plan.
Major add-ons include:
- Microsoft 365 Copilot: A generative AI assistant that integrates across Word, Excel, PowerPoint, Outlook, Teams, and more. Copilot can draft content, summarize documents, analyze data, and answer questions by leveraging organizational data and the web. It is not included in any base plan by default (as of 2025) and must be purchased separately. Pricing: $30 per user/month for the Copilot add-on. It is available for users licensed on Microsoft 365 E3/E5, Business Standard/Premium, Office 365 E3/E5, and even F1/F3. Notably, Microsoft has removed the initial requirement of a 300-seat minimum for Copilot – even a few users can be enabled. Copilot’s value depends on how much it boosts productivity for your organization – CIOs should consider piloting it with a subset of users to measure ROI before broad rollout, given the significant additional cost.
- Microsoft Defender and Security Suites: If you are on an E3 or Business Premium plan and want to enhance security without going full E5, Microsoft offers Microsoft 365 E5 Security as an add-on. This bundle (approximately $12 per user/month) includes advanced threat protection components: Defender for Endpoint (endpoint detection & response), Defender for Office 365 Plan 2 (advanced phishing & malware protection, including attack simulation), Defender for Identity, and Azure AD Premium P2 (identity protection & governance). Essentially, it brings most of the E5 security capabilities onto an E3 or Business Premium user. This can be a cost-efficient way to enhance security for specific users or the entire organization if E5’s other features (analytics, voice, etc.) are not necessary. Similarly, Microsoft 365 E5 Compliance ($12 user/month) can be added to E3/Business Premium to get the advanced compliance features of E5 (advanced audit, eDiscovery Premium, Customer Key encryption, etc.). These add-ons enable a la carte improvements in security or compliance posture without requiring a full upgrade for every user to E5. For example, a healthcare company could use E3 as its base license and add E5 Compliance for legal and compliance teams to handle eDiscovery and audit requirements, saving money compared to providing E5 to all users.
- Microsoft Viva Suite: Microsoft Viva is a modular employee experience platform that provides tools for communication, knowledge, learning, goal setting, and well-being. Some base Viva features (like Viva Connections and a basic form of Viva Engage) are free with any Microsoft 365 plan, but the premium modules require licenses. You can either buy modules à la carte (e.g., Viva Insights, Viva Learning, Viva Goals, Viva Topics, each costs a few dollars per user/month) or the Viva Suite, which bundles all modules for around $9–12 per user/month (often around $12). These are add-ons on top of your base plan. Large organizations interested in improving employee engagement, especially across distributed teams, may consider Viva. However, costs can add up, so evaluate which specific modules (if any) deliver value. Piloting one or two modules (for instance, Viva Learning for training or Viva Insights for managerial analytics) is common before deciding on the full suite.
- Teams Phone and Audio Conferencing: If you want to enable telephony (PBX) features in Microsoft Teams for users (making/receiving calls to external phone numbers), you need additional licensing. The team’s Phone System is in Microsoft 365 E5 by default; E1/E3 users can access it via an add-on (often referred to as the “Teams Phone Standard” license). Likewise, Audio Conferencing (dial-in numbers for Teams meetings) is included in E5 and can be added to E3/E1 if required. Microsoft often offers an Audio Conferencing add-on at no extra cost for enterprise agreements, but this can vary. When selecting plans, consider whether telephony is in scope. If yes, E5 includes it natively; otherwise, budget for the add-on with E3 or plan a third-party calling solution. (Note that call minutes or phone lines require separate Calling Plans or Direct Routing solutions beyond just these licenses.)
- Power Platform and Others: Other add-ons might be relevant depending on business needs. Power BI Pro is included in E5; E3 users can purchase Power BI Pro standalone (~$10 per user/month) if analytics dashboards are needed for some users. Microsoft Project and Visio have subscription plans that can be added per user. Microsoft Syntex (AI-enhanced content processing) and Microsoft Priva (privacy risk management) are newer add-ons for specialized use cases in content management and privacy, respectively. The key is that the Microsoft 365 ecosystem is modular – the base license provides core capabilities, and you can extend these capabilities via add-ons rather than upgrading the base license for everyone.
In summary, enterprise plans scale up in features and cost from E1 to E5. Frontline plans tailor those features for deskless workers with lower price points. Business plans offer small organizations bundles with a limit of up to 300 users.
Add-ons allow you to mix and match capabilities beyond the base plan. Next, we’ll discuss how to assess your organization’s needs to choose among these options.
Assessing Business Needs and Usage Patterns
Selecting the right plan starts with a clear-eyed assessment of your business requirements and usage patterns. A plan should neither leave important needs unmet nor pay for unused features. CIOs should undertake the following steps and considerations:
1. Profile Your Workforce:
Break down your users into categories such as information workers (desk-based knowledge workers), frontline workers (field or customer-facing staff), and specialized roles (executives, developers, etc.).
Determine roughly how many users fall into each category and how they work. For example:
- Do most users create and edit content heavily (requiring desktop Office apps and large storage)? Or do they primarily consume information and communicate (perhaps web apps suffice)?
- Are there teams that rarely use email or Office, but need Teams for messaging (common for frontline scenarios)?
- Identify if some roles share devices or occasionally need corporate IT services (potential for kiosk or F1 licensing).
2. Inventory Required Services:
List the services and capabilities that are must-haves for your organization. Consider:
- Email and Calendar: Nearly all organizations need Exchange email. How big are typical mailboxes? Heavy email users (e.g., those in legal or consulting) may require the unlimited archive and larger mailbox of E3/E5, while 50 GB (E1/Business) may suffice for others.
- Office Applications: Determine if users need the full desktop Office suite. If employees require offline access, advanced Excel macros, or the ability to handle large documents, desktop apps (E3 and above) are essential. If users work in a connected environment and only perform basic editing, perhaps web apps (E1) could suffice for a subset. In practice, most mid-to-large enterprises find that at least their core staff need desktop Office for productivity.
- Collaboration Tools: Microsoft Teams is a linchpin for many organizations. Ensure the plan supports the type of collaboration required, e.g., Teams with features such as meetings, screen sharing, and recording (E1/E3/E5 all include robust Teams for internal use; F plans support Teams but may have limitations, such as smaller meeting attendee capacities or read-only features). Also, consider the SharePoint and OneDrive needs for content sharing.
- Device Management & OS: If you want centralized device management (mobile device management, app pushing, conditional access), note that Intune is included with Microsoft 365 E3/E5 and Business Premium. If you’re not on those, you might need to buy Intune separately or forego that capability. Additionally, if your users need to upgrade Windows Pro to Enterprise or use virtual desktop infrastructure, having Windows Enterprise rights (included in M365 E3/E5/F3) is important.
- Security Requirements: This is a major area. Identify must-haves, such as Multi-Factor Authentication (MFA), which is available even in basic plans via security defaults. However, more advanced needs – including Single Sign-On, Conditional Access policies, Identity Protection (requiring Azure AD P2), endpoint detection and response, and threat analytics – are available with higher plans or as add-ons. If your company has experienced security incidents or has a proactive security stance, leaning toward E5 or E5 Security add-on for E3 users might be justified. On the other hand, if you already invest in third-party security tools (such as firewalls, email filters, and endpoint security software), you might decide that the built-in advanced security of E5 is redundant, and E3 is sufficient while continuing with your existing third-party solutions.
- Compliance and Regulatory: Assess your data protection and compliance obligations. For instance, are you in healthcare (HIPAA), finance (SEC, SOX), government contracting (CMMC), or under GDPR? These often require capabilities such as long-term retention, eDiscovery, audit logs, data loss prevention, and encryption. E3 provides a compliance baseline (e.g., eDiscovery Standard, DLP for documents/email, basic audit logs). E5 provides advanced tools (eDiscovery Premium with AI-assisted content search, Audit log retention for 1 year, Customer Key for encryption, Insider Risk Management, etc.). If regulatory compliance is a major driver, you may need those E5-level tools or add E5 Compliance to E3. Map out which compliance features are mandatory for you and see which plan includes them.
- Voice and Communication Needs: Does your business plan to use Microsoft Teams as a phone system (replacing PBX)? If yes, consider E5 or budgeting for the Phone System add-on. Do you need every user to be able to dial into meetings by phone or host large webinars? These features are enhanced in E5 (audio conferencing for up to 1,000 attendees, Teams Live Events, etc.). If your workforce still uses traditional telephony or another VoIP provider, you might not need the Teams telephony features and can stick with E3/E1.
- Emerging Needs (AI, Analytics): Consider if tools like Power BI or Microsoft’s AI capabilities (Copilot) will likely play a role. If data analytics for multiple users is important, having Power BI Pro included via E5 or purchasing it separately should be considered in the cost analysis. If AI automation appeals, remember it’s an add-on cost that could apply to either plan.
Listing these service requirements and their importance will help you better determine your minimum plan level.
3. Analyze Current Usage Patterns:
If you are already on Microsoft 365 (or another platform), audit how your users use their tools. It’s common to find that some users rarely use certain features.
For example, if you have E5 today, perhaps only a subset are using Power BI or Advanced Threat Protection features – could those users be targeted for a higher plan while others drop to E3?
On the other hand, you may discover pockets of under-licensed users (e.g., some users on E1 have a business need for full Office applications and are frustrated without them). Use telemetry from Microsoft 365 Admin Center or reports from your IT team to gauge:
- Average storage used (mail and OneDrive) per user.
- How many users have opened Office desktop apps vs. using only a browser?
- Security incidents or compromised accounts that can be traced to users without advanced protections.
- Feedback from departments: For example, the finance team desperately needs better data analysis tools (such as Power BI), a customer-facing team requires a phone dial-in for meetings, etc.
Understanding usage ensures you don’t over-invest or leave gaps. For instance, a manufacturing company might realize that 70% of its employees work on the factory floor and primarily use shared kiosks to check schedules and shifts.
These could be moved to F3 licenses, while the remaining 30% in offices can retain E3, resulting in significant savings with minimal impact on productivity.
Alternatively, a law firm might notice that although they have given everyone an E3, only the compliance officer utilizes eDiscovery features heavily.
If they face increasing litigation needs, upgrading a few people to E5 or getting the compliance add-on is warranted.
4. Future-Proofing and Scalability: A plan decision isn’t just about today – consider the next 3-5 years:
- Organization Growth: If you are nearing 250-300 users on Business Premium, plan to eventually transition to Enterprise (or at least be aware of the consequences of exceeding the cap). The transition from Business to Enterprise plans can be managed, but it requires planning (mailbox sizes, device relicensing, etc.).
- Global Expansion: If your company is expanding geographically, enterprise plans offer add-ons like Multi-Geo Capabilities (to store data in multiple regional data centers for data residency requirements). Multi-Geo is only available with E3/E5 in larger tenant scenarios. Industry-specific clouds (like Microsoft 365 Government GCC or Microsoft 365 for Healthcare add-ons) might also influence plan choice if you move to those environments.
- Technology Roadmap: If adopting Zero Trust security architecture, moving to cloud voice, or incorporating AI are on the roadmap, lean towards plans that won’t be a blocker. It may be more cost-effective to select a higher plan now that includes these capabilities rather than running separate projects to add them later. That said, avoid assuming “we might need this, so buy for everyone” without a timeline and adoption plans – many E5 features can be added later via add-ons or upgrades when the organization is ready to use them.
5. Independent Needs Assessment: Engaging an independent consultant or licensing expert to perform a needs assessment can be beneficial. They can conduct interviews with department heads, analyze license utilization reports, and help match business needs to Microsoft’s offerings without the conflict of selling you more than necessary.
Once you have a clear picture of your needs, you can match those to specific plans or combinations. The next section will directly link common scenarios by industry and organization type to recommended plan choices.
Matching Plans to Industry and Organization Size
Different industries and business types have distinct requirements.
Below, we outline typical scenarios and the Microsoft 365 plan (or combination of plans) that often aligns best.
These are general guidelines – every organization is unique, but industry norms can provide a starting point.
- Highly Regulated Industries (Finance, Healthcare, Legal, Government): Organizations in banking, insurance, hospitals, pharmaceuticals, large law firms, and the public sector handle sensitive data and adhere to strict regulations. Microsoft 365 E5 is often preferred for its top-tier security and compliance features. For example, a bank dealing with frequent cyber threats and compliance audits may deploy E5 to provide Defender’s advanced threat protection across all endpoints and utilize Purview’s auditing and DLP capabilities to meet regulatory requirements. Healthcare providers require HIPAA compliance – Microsoft 365 can be configured for HIPAA on any plan by signing a BAA, but E5’s advanced auditing and Customer Key encryption could add extra assurance. If full E5 for all users is too costly, a split licensing approach is common: core users (such as traders in a financial firm or doctors in a hospital) receive E5, while back-office staff receive E3. Industry example: A regional bank might license E5 for its cybersecurity team and compliance officers to leverage insider risk management and advanced eDiscovery, while giving E3 to branch office staff who mostly need Office and email. The key for regulated industries is not to skimp on necessary security/compliance – the cost of a breach or violation far exceeds the cost of a license. Also consider any Government Community Cloud (GCC) or industry cloud requirements – e.g., U.S. government contractors might need GCC High, which has E3/E5 equivalents but in a sovereign environment.
- Enterprise IT and Tech Firms: Tech companies or IT-driven enterprises often value flexibility and cutting-edge tools, but may also have engineers using specialized non-Microsoft tools. They might lean towards E3 as a base for most users, because developers and knowledge workers benefit from full Office apps and collaboration. Still, they might use alternative solutions, such as code repositories or analytics. Security is still important, but some tech companies layer their security stack, making E5’s additions less essential. However, many tech firms are early adopters of things like Copilot – so they ensure at least the plans that support it (E3/E5) and then add Copilot for relevant teams (like product management or sales content creators). Additionally, tech companies may utilize Power Platform extensively for internal applications – E3 is sufficient here, as those can be purchased as needed. Example: A 500-person software company uses E3 for all staff to get Office and Intune for device management. It provides E5 Security for the IT team, along with a handful of E5 licenses for data scientists who require Power BI Pro and advanced analytics. They keep overall costs moderate while equipping specialist roles with high-end tools.
- Manufacturing & Logistics: This sector has a mix of corporate offices and a large frontline workforce (factory workers, warehouse staff, drivers). Microsoft 365 F3 is very popular for the frontline component – workers can clock in via Teams, access training materials on SharePoint, and communicate with supervisors, all through low-cost licenses on shared tablets or their mobile devices. For the office staff (engineers, managers, etc.), E3 is generally sufficient. Suppose IP protection is crucial (e.g., protecting trade secrets in manufacturing designs). In that case, E3’s information protection may be enough, but some companies add Azure Information Protection P2 (part of E5) to classify and track sensitive files. Manufacturing firms often use third-party or on-premise systems for operations, which might not integrate with Microsoft 365 – ensure the plan doesn’t force you to pay for features you won’t utilize (for example, if using Zoom or Cisco for meetings in factories, you might not utilize Teams telephony). Example: A car manufacturer licenses 5,000 F3 licenses for factory and retail showroom staff (enabling basic email/Teams on shared devices) and 500 E3 licenses for engineers, designers, and HQ staff. They also purchase a few dozen E5 licenses for the security operations team to monitor threats with Defender. This blend addresses each group’s needs cost-effectively.
- Retail and Hospitality: Like manufacturing, these industries have many frontline employees (store clerks, hotel staff, restaurant employees) who benefit from F1 or F3 plans. Microsoft 365 F1 can suffice if workers must check schedules and receive announcements. For instance, F3 is used if you want store managers to use Office web apps for reporting. Corporate employees in these companies (marketing, corporate management) typically use E3. It’s less common for these industries to use E5 universally, unless the company is very large and concerned about centralized security for all locations. Instead, they might invest in specialized retail technology and keep Microsoft licensing lean. Example: A retail chain with 10,000 employees gives F1 to most hourly store employees (so they can access the corporate intranet and Teams for shift communications) and F3 to store managers (who edit Excel inventory sheets online). Headquarters staff (HR, finance) get E3. The company ensures compliance by training store managers on data handling, rather than purchasing E5, since they don’t handle high-risk data outside of the headquarters. Here, cost savings are prioritized while still providing essential communication tools.
- Education and Nonprofit: (While not the main focus of this playbook, it’s worth mentioning.) Educational institutions own A1/A3/A5 licensing, and nonprofits receive significant discounts (and some free E1 equivalents). CIOs in those sectors should refer to specialized plans. Still, when choosing enterprise SKUs, they often mirror government/regulated needs, or cost-saving needs, depending on whether it’s a research university (which might require E5 for data protection) or a small nonprofit (which might use mostly Business Premium to maximize donated licenses).
Organization Size Considerations:
- Small and Medium Businesses (SMB, <300 employees): Likely to go with Business Basic/Standard/Premium rather than E plans, simply due to cost efficiency. Business Premium is often the top choice as it covers security needs at a good price point for SMBs. If an SMB is approaching the 300-user mark or has ambitious growth plans, it might preemptively choose E3 to avoid a future migration.
- Mid-market (300-1000 users): This is a gray zone where some mid-sized orgs combine Business and Enterprise plans. For instance, a 500-person company could technically assign 300 users Business Premium and 200 users E3 to save money on those first 300. Microsoft currently allows this mix (300 per plan type), although they reserve the right to enforce a strict 300-cap on all Business plans in a tenant in the future. The administrative overhead of mixing plans (and ensuring feature parity) should be taken into consideration. Often, by 500+ users, many organizations standardize on E3 for simplicity, but each case varies.
- Large Enterprises (1000+): Almost always on E3/E5 mix. At this scale, enterprises might segment licensing by user personas: e.g., Persona-based licensing – executives on E5 (for the highest security and analytics), knowledge workers on E3, contractors or part-timers on E1 or F3 as appropriate. The complexity of managing thousands of user licenses makes it crucial to have a clear policy for assigning licenses and to periodically review and update it.
Global Regions and Data Residency: Microsoft 365 is available globally, and all these plans can be used in any region (with pricing varying slightly by local currency).
If your industry or company policies require data residency in specific countries (e.g., a European firm under GDPR that wants EU-only data storage), Microsoft 365 can accommodate this with region-specific tenants or multi-geo add-ons for E plans.
Additionally, some countries have specific requirements (for example, Germany has a special data center option, and China operates via 21Vianet for Office 365). Ensure your plan choice aligns with any regional needs – sometimes, certain add-ons like Power BI might store data in a particular region, or you might need to consider
Microsoft’s government or sovereign clouds operate in a regulated public sector in specific nations. These factors don’t usually change which plan tier you choose, but how you deploy it (e.g., using a GCC version of E3 vs. commercial E3).
Always confirm that the plan you select can be delivered in compliance with local laws (e.g., data localization mandates in finance or telecom sectors).
In matching plans to your industry and size, use these patterns as a reference, not a rulebook. Many enterprises adopt a tiered licensing strategy: for example, “80% of our users will be on E3, 15% on F3 (frontline and limited users), 5% on E5 (high-need users).”
This type of split often maximizes value and minimizes cost, but it requires careful management and communication to ensure that everyone understands which features they have access to. Next, we’ll outline key questions CIOs should ask to refine their decision-making process.
Key Questions CIOs Should Ask Before Deciding
Before finalizing your Microsoft 365 plan selection, it’s wise to investigate the decision with critical questions.
Here are key questions CIOs and IT decision-makers should ask:
- “What are our must-have capabilities versus nice-to-have features?” – Identify non-negotiables like compliance requirements, specific apps, or uptime needs. For instance, desktop apps (E3/E5) are necessary if on-premises Office isn’t an option. If advanced threat protection is currently lacking and causing incidents, that might be a must-have, pushing toward E5 or E5 Security add-on. Nice-to-have features (such as Power BI for all users or Teams Phone for all) can be phased in or allocated to specific groups; they shouldn’t be the sole determinant of the base plan choice without a clear use case.
- “Are we fully utilizing our current licenses?” – If you already have Microsoft 365, look at usage analytics. Perhaps you are considering E5 because it sounds good, but your E3 environment shows minimal exploitation of even E3’s security features. Conversely, maybe users are bumping into E3’s limits (e.g., running out of storage, or wanting features that say “requires E5”). A license optimization review can help determine whether upgrading or downgrading is the best course of action.
- “Can different segments of our workforce be on different plans without hindering collaboration?” – Microsoft allows mixing plan types in the same tenant. The question is whether doing so will introduce complexity in user experience or admin overhead. For example, if 20% of employees are on E5 and have access to a specific feature (such as creating Power BI reports or Advanced eDiscovery), and others don’t, will that cause friction? Often, it’s manageable (most core collaboration tools, such as emailing, editing documents, and Teams meetings, work fine across license types); however, ensure that no critical workflow assumes everyone has the higher-tier capabilities.
- “How will this decision impact our IT management and support?” – Higher-tier plans bring more tools, which can mean more management (e.g., E5’s security tools might require your IT security team to have expertise to configure and monitor them). If you choose E5, do you have the resources to fully utilize those advanced features? If not, you might pay for E5 and only use it like E3. Conversely, if you choose a lower plan, are you prepared to manage third-party solutions to fill gaps (which can increase support complexity)? The CIO should ensure the IT team is prepared for whichever path is chosen, whether leveraging Microsoft 365’s advanced suite or integrating other tools.
- “What is our plan for training and adoption of features?” – Buying a premium plan like E5 is not the end; users must use the features to realize value. Ask how you will roll out new capabilities: e.g., Will you actively use Teams Phone if you have it? Will you train users to use Purview compliance portals? If considering Copilot, how will you drive adoption? Sometimes, the answer may require organizational changes (and costs) beyond the licenses themselves.
- “Do we have any external constraints or contract considerations?” – If you are under a Microsoft Enterprise Agreement (EA), your pricing and options might be influenced. Also consider timing – if your EA is renewing soon, you may have room to negotiate if you plan to increase your license spend (or, conversely, if you are downsizing licenses, plan how to adjust without incurring penalties). Additionally, some industries may require specific data handling (e.g., client contracts may necessitate enhanced encryption, an E5 feature). Ensure your plan meets those commitments.
- “What is our budget over the next 3-5 years for user productivity and security tools?” – Look at licensing as part of a bigger IT budget. Perhaps E5 seems expensive, but it could be cost-effective if it consolidates several tools (email security, endpoint security, DLP, etc.) that you would otherwise need to purchase separately. Ask if a Microsoft-first strategy (E5-centric) or a best-of-breed strategy (E3 + third-party tools) fits your budget and philosophy. Also factor in expected Microsoft price increases – historically, Microsoft has raised prices or adjusted packaging every few years. Are you comfortable with potential increases on a higher base price? Scenario-plan the costs: “If Microsoft raises prices 10% in two years, what is the impact if we have 2000 E5 users vs 2000 E3 users with add-ons?”
- “How easily can we change course if needed?” – CIOs should know the flexibility: If you pick E3 now, can you upgrade to E5 mid-term for some or all users? (Microsoft allows upgrades and pro-rated adjustments, especially under CSP or EA licensing programs.) If you over-provision, can you downgrade licenses without penalty? (Under annual commitments, you may have to wait until renewal or pay a penalty; monthly subscription gives more flexibility at a higher cost). Ensuring you have an exit or change strategy will make you more confident in your choice. For instance, you might decide: “We’ll start with E3, and if our planned security initiative gets funding next year, we’ll upgrade to E5 or add E5 Security.” Communicate with Microsoft or your licensing partner about terms for such changes.
By asking these questions, CIOs can validate whether the choice they’re leaning toward truly aligns with business realities. The answers often highlight if more internal discussion is needed or it’s time to consult a licensing specialist.
Document the rationale for whichever plan you choose – this will help justify the decision to executives or finance (especially if choosing a higher-cost plan) and set success criteria (e.g. “we chose E5 because we expect to reduce third-party security spend by X” or “we chose E3 because we determined only 5% of users would utilize E5 features, and we will address those via add-ons”).
Now, let’s delve into cost analysis and strategies to optimize licensing costs, since budget is usually a major factor in these decisions.
Cost Analysis and Licensing Optimization Tactics
One of the CIO’s primary responsibilities is to ensure the chosen licensing is cost-effective. Microsoft 365 is a subscription model, so small per-user cost differences scale up significantly in large enterprises.
Here, we analyze the costs of the major plans and share tactics to optimize licensing spend:
Understanding Price Points (as of 2025): Rough baseline prices (per user per month, annual commitment) for reference:
- M365 E1 ≈ $10; M365 E3 ≈ $36; M365 E5 ≈ $57.
- M365 F1 ≈ $2.25; M365 F3 ≈ $8.
- Business Basic $6; Business Standard $12.50; Business Premium $22.
Enterprise plan costs have increased by 10-25% in recent years, due to new capabilities (and the separation of Teams in pricing). Always check the latest prices in your region, as Microsoft pricing can change or have promotions.
E5 is ~1.5 times the cost of E3, which is roughly 3- 4 times the cost of E1. This large delta means selecting E5 across the board could drastically increase your IT budget.
Still, it could be justified if it replaces other expenditures (e.g., eliminating separate security software licenses or reducing risk).
Licensing Optimization Strategies:
- Mix and Match License Levels: You do not have to give everyone the same license. A common cost-saving tactic is a tiered model, such as 70% E3, 30% E5, or a similar approach. Another example: a company might identify 100 users (out of 1,000) who truly benefit from E5’s extras – those 100 receive E5, while the rest remain on E3. This saves 900 * $21 = $18,900 per month compared to full E5 (using the price gap of $57 vs $36). Over a year, that’s more than $ 226,000 saved, which can fund other projects. The key is carefully identifying who needs what (use the needs assessment and usage data). Microsoft 365 admin center makes assigning different licenses to different users straightforward. Be cautious to maintain a base level of capability for all – you don’t want morale issues if some staff feel they have an inferior toolset without good reason. Communicate that it’s based on role needs, not individual value.
- Leverage Frontline (F) Plans for Appropriate Users: Frontline licenses are significantly less expensive than E licenses. If you have groups of employees who don’t need a full productivity suite or have only occasional digital engagement, moving them to F3 or F1 can slash costs. For instance, replacing an E3 ($36) with an F3 ($8) for 500 users would save approximately $ 140,000 annually. However, be mindful of the limitations (the user’s mailbox will shrink to 2GB without desktop apps, etc.). This tactic often works for roles such as shop floor supervisors, call center representatives (who mainly use a separate CRM and just need email/Teams), or temporary staff. It effectively rightsizes the license to the job function. If you make such downgrades, ensure that it truly meets their needs – e.g., verify that those users have alternative ways to perform tasks they have lost access to (perhaps they no longer need Outlook because all communication is handled through a different system or Teams). When done right, this is a highly effective optimization, and Microsoft has specifically designed F plans to serve this purpose.
- Consider Microsoft 365 Business Premium for Smaller Enterprises: If your organization is on the cusp of enterprise size (just at or above 300 users), compare the costs and features of Microsoft 365 Business Premium and Microsoft 365 E3. Business Premium at $22 offers many E3-equivalent features and some E5 security features at a significantly lower cost than E3 ($36). For 250 users, the annual difference of $14 per user is $ 3,500 per year – not trivial. Some companies with ~400 users create two tenants or use a workaround to utilize Business Premium for 300 and E3 for the rest. Be cautious: Microsoft’s licensing agreement doesn’t formally permit splitting tenants to circumvent limits, and managing multiple tenants has its complexities (separate directories, no unified Global Address List, etc.). A safer approach could be to keep 300 on Business Premium and 100 on E3 in the same tenant (which Microsoft currently appears to allow per plan type). The downside is that those 100 might not have some security features the 300 have (since Business Premium now even has some features E3 doesn’t, like Defender for Business). If you find yourself doing contortions to save money this way, it might indicate your scale has reached true enterprise level, where standardizing on E3 is simpler. However, for an organization with 200 or 250 users, Business Premium is usually the most economical choice.
- Use Add-On Suites Instead of Full Upgrades: As introduced, if you primarily need either security or compliance features of E5 but not the entire package, consider the E5 Security or E5 Compliance add-ons for your E3 users. At around $12/user each, even buying both still costs ~$24 on top of E3 (making it ~$60 total, nearly the E5 price, so usually you’d pick one focus). Many organizations choose the E3 + E5 Security add-on as an alternative to E5. This provides all the critical advanced security at $ 36 + $12 = $48, which is less than $57 for the full E5, and they forego features like audio conferencing and Power BI if not needed. Microsoft also sells “E5 Information Protection & Governance” and other mini-add-ons targeting specific features – these can be applied only to those who need them (e.g., give an Info Protection add-on just to the legal team for advanced encryption needs). This granular approach ensures you pay only for required enhancements. Work with an independent licensing expert or reseller who can outline these modular options – Microsoft’s lineup can be confusing, but navigating it correctly can be financially rewarding.
- Annual Commitment vs. Monthly and Contract Terms: Microsoft’s New Commerce Experience (NCE) licensing model imposes a ~20% premium for month-to-month subscriptions instead of annual locked plans. If you have a stable headcount and a predictable plan usage, commit to the lower annual price. Only opt for monthly term licenses for truly flexible needs (e.g., temporary contractors for 2-3 months) or if you are piloting something short-term. Additionally, enterprise agreements often lock pricing for 3 years, which can protect against increases. Negotiate multi-year agreements if you are confident in long-term needs – in exchange for predictability, you might secure discounts or at least avoid hikes. Just be careful not to overcommit licenses in an EA (you typically can increase but not easily decrease mid-term without penalties).
- Audit and Reclaim Licenses Regularly: Treat licenses as assets that need managing. When people leave the company, do you promptly remove their license and reassign or reduce the count? Some users may not have used certain services at all – can you downgrade them? Implement a process every quarter or biannually to review license assignments and usage. Tools and scripts can extract usage data (for example, who hasn’t logged into Teams in 90 days? Who hasn’t opened Office apps?). This might reveal unused licenses that can be eliminated or reallocated. Software asset management (SAM) tools or the Microsoft 365 admin reports are helpful in larger enterprises. If you find a set of E5 licenses unused, you may consider reverting to them at renewal. This continuous optimization can result in significant savings year over year.
- Keep an Eye on Promotions and Bundles: Microsoft occasionally runs promotions (especially for new services like Copilot or during an end-of-quarter sales push). Also, if you have other Microsoft products (like Dynamics 365 or Windows 365 Cloud PC), sometimes there are discounted bundles or credits. While the plan decision shouldn’t be purely promotion-driven, once you know what you need, consider whether any promotions can help reduce costs. For example, Microsoft has previously offered free Audio Conferencing add-ons or limited-time discounts on E5 to drive adoption. An independent licensing advisor or a good Microsoft account manager should inform you of these.
- Evaluate Third-Party Alternatives Critically: A cost analysis often includes “buy vs. build” or rather “Microsoft vs third-party” deliberations. Perhaps you should consider using Google Workspace instead of Microsoft 365, or sticking with on-premises Office. Those are valid strategic questions, but if you’re reading this playbook, you’re likely already set on Microsoft 365 and looking to optimize within it. However, at the feature level, you may consider third-party solutions for specific needs (e.g., Zoom for meetings, Box for storage, Okta for identity management). Using third-party tools can sometimes allow you to use a lower Microsoft plan (since you’re not using Microsoft’s full feature set). But beware: licensing overlaps can become more expensive. For example, paying for Okta while you already have Azure AD Premium in E3/E5, or paying for CrowdStrike while you have Defender. You may have very good reasons (such as best-of-breed functionality or existing contracts). It is recommended to periodically reassess whether third-party subscriptions are still necessary, considering what your Microsoft plan includes. It might be more cost-effective to consolidate on Microsoft (if their features meet your needs sufficiently) or, vice versa, drop to a cheaper Microsoft plan and let the third-party tool handle that domain. Align your spending with what provides the best value and the most user-friendly experience.
- License Reassignment for Seasonal Needs: If your business experiences seasonal workforce changes (for example, retail hiring surges during holidays or project-based contractors), leverage the ability to scale licenses up and down. Under annual plans, you can increase seats at any time and then reduce them at renewal; under CSP, you may have some monthly flexibility. Plan the timing: consider assigning higher licenses only during the necessary months (e.g., Copilot for a team only during a major project, then remove it). Alternatively, rotate a limited number of E5 licenses among users, quarter by quarter, for training/auditing purposes, rather than distributing them to everyone at once. While each user needing certain features generally needs their license concurrently, some organizations creatively manage a pool of special licenses for ad-hoc use (keeping in mind that compliance requires licenses for anyone regularly using features – don’t violate terms by pirating one license among many simultaneous users).
- Engage in Vendor Negotiations with Data: When it comes time to renew or purchase, come armed with data – your internal usage data and competitive pricing intelligence. Microsoft (or their resellers) can provide discounts, especially if you’re increasing your commitment or considering E5 upgrades. Getting quotes from multiple sources (direct vs. CSP partners) and leveraging applicable enterprise discount programs can yield savings. Ensure that you involve a procurement specialist or licensing expert to negotiate the best deal. Having documented “we have X users who will use feature Y” can sometimes get you concessions, because it shows you’ve done homework and could walk away from unneeded parts.
Real-World Cost Optimization Example:
A global manufacturing company with 8,000 employees was on Office 365 E3 for all, but after analysis, they realized 3,000 were factory and field workers who only used email and Teams occasionally. The CIO led a project to move those 3,000 to Microsoft 365 F3.
They retained 4,500 users on Microsoft 365 E3 and upgraded 500 users (executives and R&D heads) to Microsoft 365 E5 for advanced security due to targeted cyber threats in their industry.
This reallocation saved them nearly 20% on annual licensing costs, which amounted to several hundred thousand dollars. It also improved security for the high-risk group while still meeting the needs of frontline staff.
The savings were reinvested in further security training and an independent audit program, multiplying the value of the license decisions. This example underscores that understanding usage and adjusting license levels can unlock significant value.
In contrast, a financial services firm with 1,200 users moved everyone to E5, consolidating many separate tools. Their analysis showed that paying ~$21 more per user for E5 was offset by eliminating multiple other vendor contracts (legacy PBX maintenance, a cloud app security broker, a separate mobile threat system, etc.).
They negotiated a slight discount with Microsoft for the volume increase. Post-migration, their CIO reported simpler management (one ecosystem) and projected net savings in the second year after initial transition costs.
The takeaway is that cost optimization doesn’t always mean choosing the cheapest license; it means getting the most value for your spending. Sometimes, that means trading up to a higher bundle for overall cost efficiency.
Practical Recommendations and Next Steps
Choosing and implementing the right Microsoft 365 plan is a strategic decision.
Here are practical recommendations and clear takeaways for CIOs and their teams as they finalize their plan selection and move toward deployment:
1. Develop a License Strategy Document:
Synthesize everything into a clear internal policy. Outline which user segments get which licenses and why. Include exception criteria (e.g., “An employee can be elevated from E3 to E5 if their role changes to include handling confidential data…”). This prevents ad-hoc decisions and serves as a reference for your IT and HR teams when onboarding new employees or shifting roles. It also helps to justify the approach to other executives or auditors.
2. Engage Independent Expertise:
Plan to consult with an independent licensing expert or SAM consultant before making major purchases. They can validate your strategy, ensure you’re not missing hidden gotchas, and sometimes identify even more efficient licensing combinations. Importantly, they will provide neutral advice (unlike a sales rep who often aims to upsell). An expert can also assist in negotiating terms with Microsoft or optimizing your existing contract. Their fees are often minor relative to potential savings or cost avoidance in a large enterprise agreement.
3. Pilot Test the Plan (if possible):
Before a wholesale switch, consider a pilot. For example, if a chunk of users is moved to F3, test it with one department of frontline workers for a month – see if anyone complains about limitations. If upgrading to E5, consider trialing it with your security team and some power users to ensure your IT team can handle the new tools and that users see the benefits. Microsoft offers trial licenses for many plans (E5 trial, etc.), which you can leverage. This pilot can de-risk the migration and provide internal case studies. Just be careful to communicate that it’s a test, so pilot users don’t panic about lost features, or others don’t demand the new features before you’re ready.
4. Change Management and Training:
As you implement the new licensing, accompany it with a training and change management plan. For instance, if users are transitioning from desktop Outlook to using Outlook Web (as might happen when moving from E3 to F3 or E1), tips and training on using the web versions effectively should be provided. If you’re rolling out advanced features in E5 (such as Teams Phone or Power BI), provide enablement sessions so that those features get adopted. The value of a plan is only realized when users utilize its features. Allocate part of your project to user communication: highlight new capabilities they will gain (or even limitations if you remove some – frame it in the context of why and what alternatives they have).
5. Monitor Post-Deployment Usage and Satisfaction:
After making a change, closely monitor technical metrics and collect feedback. If you downgraded licenses to save costs, ensure it’s not inadvertently hampering productivity (e.g., helpdesk tickets increasing because someone lost an application). If you upgraded, ensure users leverage the new tools (e.g., track how many are using Defender dashboards or creating Power BI reports). Schedule a 3-to 6-month post-change review to evaluate whether the plan mix remains appropriate. This iterative approach ensures the licensing continues to align with any evolving business needs and resolves any unforeseen issues.
6. Keep Security and Compliance Configuration Up to Date:
This is especially true for those adopting E5 or security add-ons: simply having licenses doesn’t secure the environment, but configuration and operations do. Ensure your IT security team configures the Defender suite, sets up policies in Purview (if using), and generally operationalizes the tools included in your licenses. Microsoft provides FastTrack services and documentation to help deploy features. Also, ensure you maintain any necessary compliance documentation (if using Microsoft’s HIPAA BAA, sign it; if using Customer Lockbox or data residency controls, set them up accordingly, which might require E5 or add-ons).
7. Plan for License True-ups and Renewals in Advance:
Mark your calendar for when your subscription terms renew (annual or EA renewal) and begin the review process 3-6 months in advance. Use that time to adjust numbers (scale up/down as needed to avoid overpaying) and evaluate if a different plan makes sense due to new business circumstances. Perhaps in two years, Copilot or other AI might become so core that you decide a higher plan or an add-on for everyone is justified – budgeting and planning ahead is easier than reacting last-minute. Similarly, watch Microsoft’s roadmap – new features might shift the value proposition of certain plans (for example, if Microsoft were to add a new module to E5 exclusively, consider if it’s something you’ll need).
8. Foster Vendor-Agnostic Resilience:
While investing in Microsoft 365, ensure you’re not overly locked in without alternatives. Keep data backups (e.g., use a third-party backup for O365 if the policy requires it) and document processes so that you have leverage or options if Microsoft licensing becomes unfavorable. This doesn’t mean actively preparing to leave the platform (which is unlikely for a committed enterprise), but maintaining good IT governance. That mindset will help you treat Microsoft 365 as what it is – a service you procure for value – and keep negotiations and usage aligned to your terms.
9. Stay Informed on Licensing Changes:
Microsoft cloud licensing evolves frequently. Subscribe to Microsoft announcements or licensing blogs. For example, the separation of Teams from E plans in 2024 in certain markets was a notable change; such shifts could impact costs or how you buy (and they often provide new choices). Being aware early allows you to adapt your strategy. Perhaps in the future, Microsoft will introduce an “E7” or new bundles (some have speculated about more AI-inclusive bundles). If that happens, revisit the principles of this playbook with the new information. Having a named licensing specialist on your team or a partner can ensure you get timely updates.
10. Emphasize Value, Not Just Cost, in Communication:
Finally, when presenting the plan selection to stakeholders (such as the CFO, CEO, or IT Steering Committee), frame it around value and risk management. Rather than stating “we chose the cheapest option” or “we chose the most expensive all-in plan,” highlight how the choice meets business needs, enables productivity, secures the organization, and aligns with budget constraints.
For instance: “We will adopt Microsoft 365 E3 for most users to provide robust productivity tools and device management, while using F3 for our retail staff to significantly reduce costs on unused features.
We’ll elevate our security by adding E5 Security for critical accounts, ensuring top-tier threat protection without requiring a full upgrade of all licenses. This tailored approach saves us 15% compared to an all-E5 strategy, while mitigating risks and meeting compliance obligations. We will review this mix yearly with an independent audit to adjust as needed.” This rationale gains buy-in from business leaders and demonstrates that IT aligns technology effectively with business value.
