A 22-page report. Shelfware is licensing you pay for and never deploy — and on a Microsoft estate it accumulates by design, because the account team has every incentive to sell ahead of need and none to flag the gap. This report names the five SKUs most consistently overbought, shows you how to measure your own deployed-versus-purchased position, and gives you the reclaim sequence that converts the finding into a lower true-up and a smaller renewal.

Shelfware is not an accident; it is the predictable result of a sales model that rewards selling capacity ahead of need. These five licenses show up unused on the large majority of enterprise estates we review. For each, the report explains why it accumulates, how to measure your real deployment, and what you can reclaim before your next true-up or renewal locks the overspend in for another term.
The most expensive shelfware on most estates. E5 is sold as a security-and-analytics upgrade, then assigned broadly — but a large share of those users never touch Power BI Pro, advanced eDiscovery, Defender for Endpoint P2, or the phone system the E5 premium pays for. The report shows how to measure genuine E5 feature activation per user and where to step users back to E3 plus targeted add-ons.
Copilot for M365 was bought in optimistic blocks during 2024–2025. Months later, a meaningful fraction of assigned seats show little or no usage in the admin activity reports. Because Copilot is an add-on per assigned user, every dormant seat is pure waste. How to read the usage telemetry, set an activation threshold, and reclaim or reallocate inactive seats before they renew.
SA renews on core counts that were accurate years ago and have since shrunk through virtualisation consolidation, cloud migration, and hardware refresh. The cores are gone; the SA keeps billing. The report covers the reconciliation that matches current deployed cores to your SA count and the Azure Hybrid Benefit moves that make the surviving licenses work harder.
D365 is licensed on a base-and-attach model with a steep gap between full application licenses and the far cheaper Team Member SKU. Enterprises routinely assign full Sales or Customer Service licenses to occasional and read-mostly users whose actual usage fits Team Member rights. The report maps the access scenarios and the reassignment that captures the difference.
Power BI Pro, Power Apps per-user plans, Entra ID P2, and similar add-ons get bought for a specific initiative and never get reclaimed when it ends. They sit assigned to leavers, to disabled accounts, and to users who moved roles. The report provides the orphaned-assignment sweep that finds them and the governance to stop them re-accumulating.
Overbuying is not a one-time error; it is a steady state that the EA structure quietly protects. Each of these is addressed in the report with the measurement and the reclaim move.
The annual true-up is built to capture growth: you report and pay for increases, but mid-term you cannot hand back licenses you no longer use. Reductions are only recognised at renewal, and only if someone has measured them and put them on the table. Left unmanaged, every true-up ratchets the baseline up, and the unused capacity rides into the next three-year term as a fixed cost nobody questioned.
Admin centre license counts tell you what is assigned, not what is consumed. An E5 license assigned to someone who only opens Outlook and Teams counts as fully deployed in every standard report. Without pulling the feature-level activity data — Power BI, Defender P2, eDiscovery, audio conferencing — the overspend is invisible, which is precisely why it persists year after year.
Microsoft's commercial model rewards selling ahead of need, and the November 2025 removal of programmatic EA volume discounts pushes even harder toward higher committed quantities. Nobody on the sell side is going to tell you that 1,200 of your E5 seats belong in E3. The reclaim has to be buyer-driven — measured by you, or by an independent advisor on your side of the table — before renewal closes the window.
This report is written for the IT and procurement leaders who own the Microsoft license budget and the finance partners who have to defend it. Every section is grounded in real estate reviews, not vendor marketing — the numbers come from what we actually find when we reconcile deployed against purchased.
It reflects current Microsoft 365 and Dynamics 365 packaging, the Copilot for M365 add-on model, and the renewal dynamics heading into 2026 — including how the November 2025 removal of programmatic EA volume discounts raises the cost of carrying shelfware into your next term.

"We assumed our estate was lean because we negotiated hard on price every cycle. The deployment review found 1,300 E5 seats that belonged in E3, a block of Copilot licenses nobody had opened in four months, and Software Assurance on cores we retired two years ago. We took the reclaim into the renewal and the committed quantity dropped for the first time in the life of the agreement."
