Microsoft licensing costs have become a growing concern for organisations in 2026.

With the removal of volume-based discounts and the addition of Copilot pricing, many businesses are now paying significantly more for Microsoft 365, often without full visibility into what they are actually using.

In most cases, the issue is not overspending on purpose. It is a lack of clarity.

This guide explores how organisations can reduce Microsoft licensing costs, eliminate waste, and unlock more value from the licences they already own.

How to Reduce Microsoft Licensing Costs?

To reduce Microsoft licensing costs, organisations should review licence usage, remove inactive accounts, right-size E3 and E5 allocations, and identify tools already included in Microsoft 365. The biggest savings usually come from better visibility, not cutting capability.

Why Microsoft Licensing Costs Increased in 2026?

In late 2025, Microsoft removed volume-based Enterprise Agreement discounts.

Previously, larger organisations benefited from lower per-user pricing. That model has now been standardised.

As a result:

  • Renewal costs have increased across most organisations
  • Pricing is consistent regardless of company size
  • Copilot licences have introduced an additional cost layer

This shift has made inefficiencies far more visible and far more expensive.

Signs an Organisation Is Overpaying for Microsoft Licences

Many organisations are unknowingly overpaying.

Common indicators include:

  • High-cost licences (such as E5) assigned to users with basic needs
  • Licences still active for former employees or inactive accounts
  • Teams purchasing external tools that replicate Microsoft capabilities
  • Paying for add-ons already included in existing licence tiers
  • Underutilisation of tools like Power BI, Power Automate, or Microsoft Fabric

Many organisations discover that the capabilities they are paying for but not using are directly connected to reporting and analytics.

In fact, businesses often invest in dashboards or external tools without realising they already have access to powerful analytics within Microsoft. If you’re exploring how to make better use of your existing reporting capabilities, “Many organisations already have access to reporting tools like Microsoft Power BI but are not using them fully.

Real Example: £60,000 Saved Through Licence Optimisation

A mid-sized insurance organisation approached Synapx with a familiar challenge: Microsoft costs were increasing, but there was no clear understanding of where the inefficiencies were.

Following a structured audit, three key issues were identified:

Duplicate Capabilities

Several standalone tools were being paid for separately, despite already being included within existing licences.

Licence Tier Misalignment

Premium licences were assigned to users who required only basic functionality.

Inactive Accounts

Licences were still assigned to users who were no longer part of the organisation.

Outcome

  • £60,000 saved annually
  • No reduction in functionality
  • Previously unused tools unlocked, including Power Platform and Fabric

This type of outcome is not uncommon. Many organisations simply have not reviewed their licence estate in detail.

The 4 Most Common Microsoft Licensing Mistakes

Across industries, the same inefficiencies appear consistently.

1. Licence Tier Mismatch

High-cost licences are often assigned more broadly than necessary.

2. Shadow IT Purchases

Teams adopt external tools without awareness of existing internal capabilities.

3. Paying Twice for the Same Capability

Organisations continue renewing tools that are already bundled within Microsoft licences.

4. Underutilised Platforms

Technologies such as Microsoft Fabric and Power Platform remain unused despite being fully licensed.

Underutilised platforms are one of the biggest hidden opportunities.

Tools like Microsoft Fabric, designed to unify data, analytics, and real-time intelligence, are often already included in enterprise environments but remain unused. “Microsoft Fabric is often already available within enterprise environments but frequently goes unused.”

How to Run a Microsoft Licence Audit That Actually Finds Savings?

A licence audit should do more than count users. It should show what people are actually using, where money is being wasted, and what capabilities are already available but underused.

Step 1: Map your current licence estate

Start by building a full view of:

  • all Microsoft 365 licences assigned
  • user counts by licence type
  • add-ons such as Copilot, Power BI Pro, Audio Conferencing

Use:

  • Microsoft 365 Admin Centre billing reports
  • Entra ID user lists
  • Azure cost management (if relevant)

This gives a clear picture of your current spend.

Step 2: Compare licence allocation against actual usage

This is where most savings are found.

Review:

  • inactive users still assigned licences
  • E5 users only using email and Teams
  • users not using premium security / compliance features
  • Copilot licences with low adoption

Use:

  • Microsoft 365 usage analytics
  • adoption reports
  • sign-in logs in Entra ID

This helps identify where licence tiers can be reduced without affecting productivity.

Step 3: Review duplicate tools and shadow IT spend

Many businesses pay twice for the same capability.

Look for:

  • third-party workflow tools already covered by Microsoft Power Automate
  • separate BI tools when Microsoft Power BI is already licensed
  • manual reporting work that could be improved using Microsoft Fabric

This often reveals savings outside licensing itself.

Step 4: Identify underused Microsoft capabilities

A lot of businesses are paying for tools they have never properly adopted.

This often includes:

  • automation workflows
  • reporting tools
  • collaboration features
  • security functionality

A licence audit should not just cut costs. It should also show where more value can be unlocked from your existing Microsoft investment.

Should You Buy More Copilot Licences or Optimise First?

CBefore buying more Copilot licences, most organisations should first check whether their Microsoft environment is ready.

Copilot delivers the most value when:

  • files are well organised in SharePoint
  • Teams usage is consistent
  • permissions are managed properly
  • core Microsoft 365 adoption is already strong

If those foundations are not in place, buying more Copilot licences can increase cost without improving productivity.

For most organisations, optimising the Microsoft estate first leads to better results and lower long-term spend.

A Common Misconception About Microsoft Licensing

Many organisations assume that unlocking new capabilities requires additional licences.

In reality, a significant portion of functionality is often already available within existing agreements.

This is particularly true for:

  • Automation (Power Automate)
  • Analytics (Power BI)
  • Data platforms (Microsoft Fabric)

The challenge is not access; it is awareness and implementation.

The Bottom Line

Microsoft licensing is no longer just an operational concern.

In 2026, it is a strategic lever that directly affects cost efficiency and scalability.

Organisations that perform well in this area tend to ask four key questions:

  • What are we paying for?
  • What are we actually using?
  • Where are we overspending?
  • What capabilities are we not leveraging?

In most cases, the issue is not cost; it is visibility.

Still unsure where your Microsoft spend is going?

Most organisations are paying for tools they don’t use and missing value in the ones they already have.

Frequently Asked Questions

Microsoft removed volume-based EA discounts for online services in November 2025. Previously, larger organisations received tiered pricing; the more licences you bought, the lower the per-seat cost. That structure is now gone. All EA customers pay standardised list pricing regardless of size. Organisations previously on higher volume tiers are facing renewal cost increases of 5–15%, making licence optimisation more commercially significant than it has been for years. 

The clearest indicators are: E5 licences assigned to users who only use core productivity tools, standalone subscriptions for tools already included in your licence tier, active licences assigned to former employees or inactive accounts, and tools within your estate that have never been activated. A formal licence audit will surface all of these. Most organisations we work with find meaningful savings within the first structured review. 

Microsoft 365 E3 covers core productivity (Outlook, Teams, SharePoint, Office apps) plus standard security and compliance features. E5 adds advanced security, compliance, voice, and analytics capabilities. E5 costs roughly 50–60% more per user than E3. For most knowledge workers, E3 is sufficient. E5 is justified for roles with elevated security requirements, compliance responsibilities, or heavy Power BI and analytics usage. Auditing whether your current E5 assignments reflect genuine need is typically where the largest single savings opportunity sits. 

In most cases, yes. The goal of a licence optimisation exercise is not to remove access, it’s to ensure the right users have the right licence tier. Users who moved from E5 to E3 don’t lose the tools they actively use; they move to a licence that reflects actual usage. Where tools would genuinely be lost, the audit identifies this in advance, so every decision is made deliberately, not by accident. 

It depends entirely on your starting point. Organisations with a clean, well-governed Microsoft 365 environment, structured SharePoint, good content tagging, and active Teams usage typically see strong Copilot ROI relatively quickly. Organisations without that foundation find that Copilot amplifies the disorganisation rather than solving it. Our recommendation is always to run a license and readiness audit before committing to Copilot at scale. It tells you whether you’re ready, and for which users
