The M365 licensing audit checklist

A short list that often saves 20-30% on Microsoft 365 spend in the first review.

By franklin

Most M365 estates we audit have a quiet 20-30% of unused or wrongly-tiered licences. Here is the checklist we run.

Inventory

  • Pull all assigned licences from the admin centre
  • Match to HR active-employee roster
  • Flag accounts inactive > 60 days

Tier-fit

  • F1/F3 for frontline staff using kiosk apps only
  • Business Premium for SMB knowledge workers
  • E3 only when Azure AD P1 / Intune / DLP needed
  • E5 only when justified by Defender, Power BI Pro, audio conferencing or compliance add-ons

Add-ons hiding in plain sight

  • Visio, Project, Power BI, Power Automate
  • Defender for Office 365 P1 vs P2
  • Teams audio conferencing
Go line by line. The savings fund the rest of the engagement.
