M365 Optimization: Remove Shelfware. Rightsize Seats.

Microsoft 365 is the largest single licence line for most enterprises — and the most consistently over-licensed. The average enterprise carries 15 to 25 percent M365 shelfware: inactive accounts, over-provisioned E5 licences where E3 is sufficient, add-ons that duplicate capabilities already included in base tiers, and Copilot licences that were purchased aspirationally but are not actively deployed. Independent optimization identifies and eliminates each category.

Frequently Asked Questions

How do you identify M365 shelfware?+

We cross-reference M365 licence assignments against Azure AD user activity logs, showing login frequency, application usage, and feature adoption. Inactive accounts, disabled users, and service accounts assigned premium tiers surface immediately. We also audit add-on assignments against feature usage from security logs.

Can M365 licences be removed mid-EA term?+

Yes. Seat reductions, tier downgrades, and add-on removals are allowed at any time during an EA term. Microsoft will adjust your monthly or annual billing. However, some add-ons have minimum commitment periods—we review your specific terms and optimize within those constraints.

What is the difference between M365 E3 and E5?+

E3 includes Office, Teams, SharePoint, and OneDrive. E5 adds advanced security (Microsoft Defender), compliance (Purview), and analytics (MyAnalytics). For users who don't require advanced security/compliance, E3 is sufficient. E5 is typically justified only for security teams, compliance roles, and executive users.

How does M365 Copilot licensing work?+

M365 Copilot is a separate add-on (£20/user/month) that requires E5 base licence. Copilot Pro (consumer version) is separate from M365 Copilot. Many enterprises license Copilot speculatively before full rollout—we identify actual users vs. licensed but unused seats and adjust.
