Microsoft 365 License Optimization Framework 2026

Q: What is addressable seat framework?

The broader Microsoft 365 addressable seat framework anchors the broader Microsoft 365 framework against the broader actual customer Microsoft 365 user framework, with the broader Microsoft 365 addressable seat framework typically anchored on the broader knowledge worker framework. The broader Microsoft 365 addressable seat framework typically excludes the broader frontline worker framework, the broader contractor framework, the broader low utilisation framework, and the broader inactive user framework, with the broader Microsoft 365 addressable seat framework typically anchored on the broader Microsoft Entra ID framework.

Microsoft 365 license optimization is the load bearing buyer side framework on the broader Microsoft 365 commercial framework. It anchors the Microsoft 365 framework against the actual customer user count, the actual edition mix, the actual utilization telemetry, and the actual reclamation cohort.

The buyer side analysis is that the Microsoft 365 framework typically over runs the actual customer user framework by between ten and twenty five percent.

This article sets out the Microsoft 365 license optimization framework across five lenses:

Edition mix. Right sizing E3, E5, F1, F3 and Office 365 E3 against the actual user cohort.
Addressable seat. Anchoring the knowledge worker cohort and excluding frontline, contractor, low utilization, and inactive users.
Reclamation. Reclaiming leaver, inactive, low utilization, and contractor seats on a ninety day cadence.
Add on rationalisation. Anchoring Defender, Purview, Entra ID Premium, Intune, Power BI Pro, and Project against actual add on utilization.
Commercial framework. Anchoring the EA price hold framework against the Microsoft annual commitment.

The license inventory framework

The Microsoft 365 license inventory framework anchors the Microsoft 365 estate against the actual customer contractual annual commitment, typically inside the Microsoft Enterprise Agreement framework.

The inventory framework typically spans these SKUs:

Microsoft 365 E3. Knowledge worker baseline.
Microsoft 365 E5. Knowledge worker premium bundle with Defender, Purview, and Power BI Pro.
Microsoft 365 F1 and F3. Frontline worker tiers.
Microsoft 365 Business Standard and Business Premium. Small and mid market estates.
Office 365 E3 and E5. Office only tiers where Windows and security are licensed separately.

The buyer side move is to anchor the inventory framework against the actual annual commitment, with Microsoft Entra ID as the source of truth on the user list. Read the related Microsoft 365 license optimizer.

The edition mix framework

The Microsoft 365 edition mix framework anchors the E3, E5, F1, F3, and Office 365 E3 SKUs against the actual customer user cohort.

The edition mix framework typically segments users into three cohorts, with Microsoft Entra ID as the source of truth:

Knowledge worker. Full productivity, collaboration, and analytics. E3 or E5 baseline.
Frontline worker. Shared device, single sign in, limited storage. F1 or F3 baseline.
Contractor. Short tenure, restricted access. Typically F3 or no internal SKU.

The buyer side move is to right size the edition mix against the actual user cohort. The framework typically delivers between five and twenty percent off the Microsoft 365 list framework. Read the related M365 cost per user 2026.

The addressable seat framework

The Microsoft 365 addressable seat framework anchors the Microsoft 365 estate against the actual customer user cohort, typically narrowed to the knowledge worker population.

The addressable seat framework typically excludes:

Frontline workers. Sized into F1 or F3 instead of E3 or E5.
Contractors. Out of scope of the E3 or E5 commit.
Low utilization users. Less than the agreed activity threshold over the trailing ninety day window.
Inactive users. No activity on Microsoft Graph telemetry over ninety days.

The buyer side move is to anchor the addressable seat count against the actual user cohort, cross referenced against Microsoft 365 utilization telemetry rather than the legacy headcount export. Read the related Microsoft Copilot cost per user.

The reclamation framework

The Microsoft 365 reclamation framework anchors the Microsoft 365 estate against the actual customer user cohort, with Microsoft Entra ID as the source of truth on the user list.

The reclamation framework typically targets four cohorts:

Inactive users. No activity on Microsoft Graph telemetry over ninety days.
Low utilization users. Activity below the agreed threshold on Word, Excel, PowerPoint, Outlook, Teams, OneDrive, and SharePoint.
Leavers. Disabled Entra ID accounts still holding paid licenses.
Contractors. Short tenure users on the premium SKU.

The buyer side move is to anchor the reclamation framework on a rolling ninety day inactive user query. The framework typically delivers between five and fifteen percent off the Microsoft 365 list framework. Read the related M365 license reclamation guide.

The add on framework

The Microsoft 365 add on framework anchors the add on estate against the actual customer add on consumption, typically inside the Microsoft Enterprise Agreement.

The add on framework typically spans:

Microsoft Defender. Endpoint, Identity, Office 365, and Cloud Apps modules.
Microsoft Purview. Information protection, data loss prevention, eDiscovery, and compliance.
Microsoft Entra ID Premium. Conditional access, identity protection, and privileged identity management.
Microsoft Intune. Endpoint management and mobile application management.
Microsoft Power BI Pro. Self service analytics and shared workspaces.
Microsoft Project. Project management.

The buyer side move is to anchor each add on against actual utilization, not against the headcount on the master EA. Read the related M365 security unbundled.

The utilization framework

The Microsoft 365 utilization framework anchors the Microsoft 365 estate against actual usage telemetry, with Microsoft Graph as the source of truth.

The utilization framework typically spans seven workloads:

Microsoft Word. Document authoring.
Microsoft Excel. Spreadsheet authoring and analysis.
Microsoft PowerPoint. Presentation authoring.
Microsoft Outlook. Mail, calendar, and meeting workflows.
Microsoft Teams. Chat, meetings, and collaboration.
Microsoft OneDrive. Personal cloud storage and file sync.
Microsoft SharePoint. Team and project sites.

The buyer side move is to anchor the utilization framework on rolling ninety day usage telemetry, not on the legacy headcount baseline. Read the related Microsoft 365 license optimizer.

The commercial framework

The Microsoft 365 commercial framework anchors the Microsoft 365 estate against the Microsoft Enterprise Agreement on an annual commitment basis, with the commitment matched to the actual customer contractual baseline.

The commercial framework typically rolls up five upstream levers:

Edition mix. The E3, E5, F1, F3 SKU split.
Addressable seat. The knowledge worker baseline.
Reclamation. Inactive, leaver, and low utilization seats.
Add ons. Defender, Purview, Entra ID Premium, Intune, Power BI Pro, and Project.
Utilization. Workload telemetry from Microsoft Graph.

The buyer side move is to anchor the commercial framework against the EA price hold framework, locking each lever for the duration of the term. The framework typically delivers between ten and twenty five percent off the Microsoft 365 list framework. Read the related Microsoft EA Renewal Playbook.
