Microsoft 365 License Right Sizing Service

Microsoft's playbook pushes uniform E5 for everyone. Usage data tells a different story: distinct user profiles, unused functionality, and third party tools covering the same ground. We size the estate from the evidence.

Estates paying E5 prices for E3 usage

This engagement is bought by IT asset managers and CIOs whose Microsoft 365 bill has crept toward uniform E5 coverage, justified at some point by security bundling and simplicity, and never revisited against what users actually consume. The renewal is approaching, the July 2026 price increases have landed, and finance wants the seat mix defended with data.

It also serves organizations that suspect double payment: an E5 security stack alongside third party tools doing the same job, add ons nobody remembers buying, and license counts that never shrank when headcount did. The typical estate we profile carries 15 to 30 percent addressable waste.

What we solve

Where the M365 money leaks

Microsoft 365 overspend concentrates in five places, all measurable from your own admin center data:

  • Uniform E5 coverage across user populations whose usage justifies E3 or F3, with the premium paid on every seat every month.
  • Duplicate coverage: E5 security, telephony, analytics, and device management components paid for while third party tools cover the same ground.
  • Inactive accounts, departed users, and service accounts still holding full suites.
  • Add ons and standalone licenses overlapping suites that already include the capability.
  • Contract terms that only permit reductions at specific dates, so unplanned estates miss the window renewal after renewal.

Each finding is quantified from usage evidence, so the savings case survives both internal challenge and Microsoft's renewal counterattack.

How we do it

Baseline, segment, clean up, cash in

The engagement follows the four workstreams of our M365 right sizing statement of work. Assigned licenses are matched against service level usage, users are segmented into profiles mapped to the correct level, duplicate coverage and hygiene findings are quantified, and everything lands in a movement plan timed to your enrollment dates.

Workstream 01
License and usage baseline
Assignment and service level usage data analyzed into a per user view of license, active services, intensity, and cost, with the contractual flexibility for reductions mapped.
Workstream 02
Profile segmentation
User profiles defined from demonstrated need and mapped to the correct mix of E5, E3, F3, and add ons, with security requirements checked so downgrades create no capability gaps.
Workstream 03
Duplicate coverage and hygiene
Overlap between suite components and third party tools assessed with a consolidation direction per overlap, plus inactive accounts, service accounts, and unused add ons quantified.
Workstream 04
Savings case and renewal alignment
All findings consolidated into one savings case, sequenced against enrollment anniversary and renewal dates, with the negotiation positions to defend the mix against E5 pressure.

Pacing follows the statement of work: the baseline report lands within 10 business days of complete usage data, with segmentation and cleanup analyses following in the next cycle. Movement lands when your contract permits it, which is why the plan is sequenced to enrollment dates. Navy bars are analysis and build, gold diamonds mark a deliverable handover, gray bars run on demand. Weeks are indicative for a typical estate; renewal dates and vendor deadlines set the real clock.

Why buy this service

Usage data beats the bundle pitch

Microsoft's E5 consolidation argument is well rehearsed: security is included, simplicity saves money, and everyone is moving up. It survives only where nobody has profiled the estate. A per user view of what is actually consumed is the one argument the account team cannot bundle away.

The practice behind this service has delivered more than 200 Microsoft engagements across Enterprise Agreements, Azure, Copilot, and support, so the right sizing lands as part of a coherent renewal strategy rather than a spreadsheet Microsoft picks apart seat by seat.

We resell nothing: no Microsoft agreements, no third party tools competing with E5 components, no security stack of our own to defend. When the right answer is keeping E5 for a population, that is the recommendation, with the evidence attached.

One fixed, all inclusive fee covers all four workstreams, up to four advisory calls, and email support through the term, or a contingency structure where the fee comes only from savings delivered. First deliverable inside 10 business days of complete data.

Frequently asked questions

Questions we hear first

How much waste does a typical Microsoft 365 estate carry?

15 to 30 percent of spend is the typical addressable range: E5 seats justified by E3 usage, duplicate coverage against third party tools, inactive and departed accounts, service accounts on full suites, and forgotten add ons.

Does everyone really not need E5?

Some populations genuinely do, and the analysis says which. Most estates split into distinct profiles, and a mixed E5, E3, F3 model priced from measured usage almost always beats uniform coverage. Where E5 is justified, you keep it with evidence.

What about the security capabilities in E5?

Security requirements are assessed per profile before any downgrade is recommended, and the duplicate coverage analysis often finds the same capability already paid for twice, once in E5 and once in a third party tool. The consolidation direction is a decision, not a default.

Can we actually reduce licenses mid term?

Reductions land at the dates your enrollment permits, which is exactly why the movement plan is sequenced against enrollment anniversary and renewal. Missing the window is how estates stay oversized for another three years.

What data do you need from us?

License assignment and service level usage data from the Microsoft 365 admin center and available reporting, the enrollment and pricing documents, and an inventory of add ons and third party tools in the overlap categories.

Will Microsoft push back at renewal?

Yes, with the standard E5 consolidation arguments. The engagement includes the negotiation positions and responses to defend the right sized profile, and the usage evidence makes them hard to argue with.

How does this relate to Copilot?

Directly: Copilot pricing stacks on top of the underlying suite, so an oversized M365 estate inflates the AI conversation too. Our separate Copilot optimization service handles seat level AI right sizing; this engagement fixes the foundation.

How is the engagement priced and how fast does it run?

Fixed price, all inclusive, covering all four workstreams, up to four advisory calls, and email support, or contingency from delivered savings. The baseline report typically lands within 10 business days of complete data.
