Many organisations assume that buying Microsoft 365 licences ensures productivity, protection, and compliance.
But the truth? Most businesses pay for features they don’t use - or worse, misuse licences entirely.
The Reality We Find in Health Checks
In nearly every M365 audit we run, we discover:
E5 licences issued to users who only use email
Power Automate assigned but unused
Teams Phone or Audio Conferencing licences active with zero activity
Project and Visio licences assigned broadly, but only used by a handful
Shared mailboxes with paid user licences
Orphaned licences still consuming cost
These aren’t edge cases - they’re the norm.
“Set and Forget” Licensing Costs You
M365 environments evolve rapidly, but licensing rarely keeps up:
Users leave, and licences stay active
New features get added - but never adopted
Business units deploy tools outside of IT oversight
Without visibility, licence sprawl becomes silent waste.
Value ≠ Activation
You might have Defender, Purview, or Copilot enabled. But are they:
Configured?
Monitored?
Used effectively?
Most environments activate services - but don’t govern or measure outcomes.
It’s Not Just About Savings
Optimising licensing isn’t just a financial exercise - it’s strategic:
Enables better budget forecasting
Reduces compliance risk
Improves support and lifecycle governance
Strengthens ROI conversations at the board level
What Our M365 Optimisation Health Check Delivers
We uncover:
Licence underutilisation
Misaligned entitlements
Redundant third-party tools
Persona-based licensing opportunities
Cost attribution and governance gaps
If you’ve never audited your M365 usage - start now.
Our Optimisation Health Check finds the inefficiencies your admin centre won’t.
We benchmark your overall Microsoft 365 configuration against Microsoft Secure Score and Zero Trust principles. It surfaces configuration drift, license misalignment, and operational risks across identity, device, data, and compliance services.
