Microsoft 365 Licence Optimisation: Stop Overpaying Before Your Next Renewal

Why M365 Licence Optimisation Is Urgent in 2026

Two structural changes in 2025 and 2026 have permanently increased the cost of unoptimised M365 licensing. First, Microsoft removed its EA volume discount tiers B, C, and D in November 2025. Organisations that previously received automatic 15 to 25 percent volume discounts now start at Level A pricing, with additional discounts available only through active negotiation. Second, Microsoft's July 1, 2026 pricing update increases list prices across the M365 SKU stack — E3 from $36 to $39, E5 from $57 to $60, and frontline SKUs with increases of 25 to 33 percent. The M365 SKU hierarchy now runs from E1 through E3, E5, and E7, with E7 as the current top tier. Microsoft field teams are actively pushing E5 customers toward E7 at renewal — a further potential cost increase that needs to be evaluated against actual capability requirements, not accepted by default.

For an organisation with 10,000 M365 seats, the combined impact of discount tier removal and pricing increases can represent $300,000 to $600,000 in additional annual spend — before factoring in any SKU mix waste that has accumulated through the prior agreement term. Licence optimisation is not a nice-to-have exercise before renewal; it is a financial necessity.

What M365 Licence Optimisation Covers

SKU Mix Audit: Are People on the Right Plan?

The SKU mix audit compares actual feature usage — drawn from the Microsoft Admin Center's usage reports — against the licence tier assigned to each user. The common findings are E5 users who are not activating any E5-exclusive security or compliance features (and could be right-sized to E3, saving $21 per user per month at current pricing), E3 users who have not activated desktop Office installations and meet F3 eligibility criteria, and frontline workers assigned E3 when F1 or F3 provides all required functionality at a fraction of the cost.

In a population of 10,000 users, a SKU mix audit typically finds 15 to 25 percent of licences deployed at the wrong tier. At $21 per user per month difference between E5 and E3, a 15 percent misassignment rate on a 10,000-seat estate represents $378,000 per year in direct licence savings.

Inactive and Unassigned Licence Identification

Industry-wide data shows that 56 percent of enterprise M365 licences are inactive, underutilised, or unassigned. Unassigned licences — paid but not provisioned to any user — are pure waste. Inactive licences assigned to users who have not logged in within 90 days require review: the user may have left the organisation, changed role, or be on extended leave. Inactive licence identification is typically the fastest-return optimisation activity, with savings achievable within weeks of an audit.

Add-On Licence Redundancy Analysis

M365 licence estates frequently accumulate add-on licences procured independently of the core SKU structure — Defender for Endpoint P2, Entra ID P2, Microsoft Purview compliance modules, Teams Phone, Teams Rooms, Copilot Studio. Many of these are included in higher-tier SKUs the organisation is already paying for. Mapping each add-on licence against the core SKU's included entitlements routinely identifies 5 to 10 percent of total contract value in redundant add-on spend.

True-Up Management

The annual EA True-Up requires organisations to report and pay for any net-new licence growth over the EA's committed baseline. True-Up surprises — unexpected licence additions that trigger large annual payments — are one of the most common sources of M365 budget overruns. Proactive True-Up management involves modelling True-Up liability at six months before the True-Up date, identifying any deployments that have grown beyond the committed baseline, and assessing whether right-sizing steps can reduce True-Up exposure before the reporting period closes.

EA Negotiation: The Pricing Layer of Optimisation

Licence optimisation addresses the quantity and mix of licences. EA negotiation addresses the unit price. Both levers are necessary for a comprehensive M365 cost reduction programme.

With EA discount tiers removed, the gap between organisations that negotiate well and organisations that accept Microsoft's opening commercial position has widened. A buyer who accepts Level A pricing at 5 percent off list will pay materially more than a buyer who enters the EA negotiation with competitive benchmarking data, documented usage evidence, and awareness of Microsoft's current field rep incentive structure. In Q4 — April through June — Microsoft's field teams are under maximum pressure to close before the June 30 fiscal year end. This is the highest-leverage window for EA negotiations and it is open right now.

Standard EA discounts that are achievable through active negotiation in 2026 are 10 to 20 percent off the new list prices — down from historical 15 to 25 percent, but still meaningfully better than the default Level A position. For a 10,000-seat M365 E3 estate at new list of $39 per user per month, the difference between 5 percent and 15 percent discount is approximately $470,000 per year. An optimised negotiation more than justifies specialist advisory support.

The E7 Upsell: How to Evaluate It Objectively

Microsoft's commercial field teams are actively pushing E5 customers to upgrade to E7 — the new top M365 SKU above E5. E7 bundles Microsoft 365 Copilot ($30 per user per month as a standalone add-on), advanced security, and enhanced compliance capabilities previously sold as E5 add-ons. At first presentation, E7 can appear as a consolidation play that eliminates several separate add-on purchases.

In practice, E7 upgrade decisions require objective analysis. Many E5 organisations are not using the full E5 feature set — upgrading to E7 when the organisation has not deployed the Defender XDR, Purview, or Entra ID P2 capabilities in E5 adds further unused entitlements at greater cost. The correct sequence is: audit E5 utilisation first, right-size users who do not need E5 to E3, and then evaluate E7 only for the population that is actively consuming E5 capabilities and has genuine Copilot and advanced AI requirements.

Accepting the E7 upgrade for the entire E5 population without this analysis is the most expensive possible outcome. Redress Compliance's Microsoft EA advisory specialists include an objective E7 upgrade assessment as a standard component of any EA renewal engagement.

What Independent Optimisation Looks Like

Microsoft's own licence optimisation assessments — conducted by Microsoft account teams or Microsoft-aligned partners — have an inherent conflict of interest. Microsoft's compensation model rewards higher licence counts and E7 upgrades, not the savings that come from right-sizing to E3 or F-series SKUs. Assessments conducted by Microsoft field teams routinely recommend upgrades and additions, not reductions.

Independent M365 licence optimisation, conducted by a specialist with no Microsoft vendor relationship and no incentive tied to licence volume, produces materially different outcomes. At Redress Compliance, every M365 licence optimisation engagement is conducted entirely on the buyer side — we receive no referral fees, reseller commissions, or Microsoft partner incentives of any kind. Our only commercial objective is reducing the client's total M365 cost and improving their EA negotiation position.

In 500+ enterprise software licensing engagements across EMEA and North America, Redress Compliance has consistently found significant optimisation opportunities that vendor-side or partner-side assessments had not identified. The typical outcome of an independent M365 licence optimisation is a combination of 10 to 20 percent reduction in annual licence spend through right-sizing and 10 to 20 percent improvement in negotiated EA unit pricing — with total combined savings typically in the 15 to 30 percent range of the annual M365 contract value.

How the Redress Compliance M365 Optimisation Process Works

The engagement begins with data collection: licence assignment exports, usage reports from the Microsoft Admin Center, EA contract documentation including the current price sheet and True-Up history, and a role mapping exercise to understand how different user populations use M365. This data collection takes three to five business days with standard IT team cooperation.

Phase two is analysis: SKU mix modelling against actual usage, add-on redundancy mapping, True-Up liability projection, E7 upgrade assessment, and benchmarking of the current EA pricing against comparable enterprise agreements from our database. The analysis phase typically runs five to ten business days and produces a detailed savings opportunity report with specific recommendations, quantified savings projections, and implementation risk assessment for each recommendation.

Phase three, where requested, is EA negotiation support: preparing the commercial brief, providing negotiation coaching, attending EA renewal discussions as an independent advisor, and reviewing final commercial terms before signature. Our negotiation engagements consistently achieve savings above what clients achieve independently, with the advisory fee covered multiple times over by the improvement in commercial terms.
