Home/Microsoft 365/E5 Downgrade Analysis
Cost Optimization · M365 Tiering

Most E5 estates are half consumed. The honest math says so.

E5 carries roughly seven exclusive workloads on top of E3. Across every engagement we have run, the active utilization of those exclusive workloads sits between thirty five and fifty five percent of the attached population. The remainder of the seats are paying for the bundle to access entitlements they already had on E3. The E5 downgrade analysis is the workload by workload utilization test that produces a defensible tiering recommendation. It is also the precondition for activating any step down clause negotiated in the EA.

What E5 actually adds

The exclusive workloads. Seven of them.

E5 is E3 plus a defined exclusive bundle. Knowing the bundle is the precondition for testing utilization. Treating E5 as a generic premium tier produces sloppy analysis.

Security and identity
Three workloads

Defender Plan 2, Entra ID P2, Defender for Cloud Apps

The three security workloads that carry the heaviest perceived value in the E5 bundle. They are also the ones most commonly entitled and least commonly used end to end.

  • Defender for Endpoint Plan 2. Endpoint detection and response. Signal: rolled out at the endpoint enrollment level.
  • Entra ID P2. Identity governance, risk based conditional access. Signal: policies configured and risk events processed.
  • Defender for Cloud Apps. Cloud app discovery and control. Signal: app catalog populated and policies authored.
Compliance, analytics, voice
Four workloads

Purview Premium, Power BI Pro, Teams Phone, Audio Conferencing

The remaining four exclusive workloads. Each one is testable with telemetry. None of them is binary on or off at the user level.

  • Purview eDiscovery Premium and Insider Risk Management. Signal: cases and policies in production.
  • Power BI Pro. Signal: user authentication against the Power BI workspace.
  • Teams Phone with Calling Plan. Signal: phone number assigned and call records present.
  • Audio Conferencing. Signal: dial in usage on Teams meetings.
The utilization test

Per workload. Per user. Ninety days.

The honest test is whether each user authenticated against, or generated activity for, each of the seven exclusive workloads inside the previous ninety days. The aggregation produces a tiered population.

Tier A

Genuine E5

Users with documented activity on three or more of the seven exclusive workloads inside the ninety day window. Step down is not appropriate. The bundle is consumed.

  • Typical share. Twenty to thirty five percent of the attached E5 population.
  • Action. Maintain E5 attach.
Tier B

E3 plus targeted

Users with documented activity on one or two of the seven exclusive workloads. Targeted standalone attach to E3 is cheaper than the full E5 bundle for this population.

  • Typical share. Thirty to forty percent of the attached E5 population.
  • Action. Step down to E3 and attach the specific workload as a standalone.
Tier C

Pure E3 candidate

Users with no documented activity on any of the seven exclusive workloads. The full E5 premium is being paid for entitlements that are never exercised.

  • Typical share. Thirty to forty five percent of the attached E5 population.
  • Action. Step down to E3 with no add ons attached.
The financial model

The dollar consequence at scale.

The downgrade analysis stays academic until it is translated into a multiyear dollar position. Three line items make the case at the renewal table.

Line 01 · Base SKU recovery

Per user, per month, per term

E5 to E3 step down at typical large enterprise concession bands recovers roughly $25 to $32 per user per month. For a five thousand seat Tier C population the annual recovery on the base SKU alone reaches $1.5M to $1.9M. Across a three year term, $4.5M to $5.7M.

For Tier B, the net recovery is smaller because the targeted attach restores some of the spend. The net usually lands at $12 to $18 per user per month, still material across a population in the thousands.

Line 02 · 03 · Compounding effects

True up reduction and renewal anchor

The downgrade analysis also produces a cleaner true up forecast. Year one and year two true ups reflect the corrected tier mix rather than the inflated baseline. The reduction compounds across the term.

At renewal, the corrected mix becomes the new anchor for negotiation. The next term prices off a defensible E5 attach percentage rather than an aspirational one. The renewal conversation starts from the same number procurement spent the term proving.

The advisory model

What we deliver in a downgrade engagement.

The downgrade engagement runs in two phases. The diagnostic phase produces the tiered population. The contracting phase converts the tier mix into a defensible renewal position.

Phase 01 · The diagnostic

Telemetry, tiered population, dollar model

We pull workload telemetry across the seven E5 exclusive workloads, run the ninety day utilization test, and tier the population into A, B, and C. The deliverable is a per user disposition with an attached financial model showing recovery against current spend.

The diagnostic also surfaces the second order opportunities. Defender Plan 2 step down to Plan 1 for partial users. Power BI Pro removal from users who do not authenticate. Teams Phone removal from users in the wrong country footprint. Each is an additional recovery item.

Phase 02 · The contracting move

Step down clause at renewal

The tier mix is the input to the renewal negotiation. The buyer enters with documented Tier C and Tier B populations, a defensible step down position, and the contract language to lock the change in at anniversary.

The asymmetric value is that Microsoft account teams negotiate against an evidenced position rather than an aspirational one. The conversation shifts to which workloads warrant attach, not whether E5 is correct in aggregate. That shift is the negotiation.

The tiered population is the input to the negotiation, not the output. Microsoft will not run this analysis for the buyer. The diagnostic belongs upstream of the quote.
