A license review starts with what the business needs to keep working. A lower invoice is only an improvement if email, files, security controls, and required records remain available. Collect evidence first, then approve changes in a controlled sequence.
Build one inventory from several sources
The invoice, the tenant's subscription list, and the employee roster answer different questions. Compare them rather than assuming any one is complete. Include contractors, shared resources, service accounts, and subscriptions purchased through a reseller.
Record the review date and the person who can approve changes. If a subscription cannot be matched to a known owner or purpose, investigate it before marking it for removal.
- Active staff and contractors, including role and department
- Assigned licenses and enabled services for each account
- Purchased quantities, renewal dates, and billing owner
- Shared mailboxes, application accounts, and integrations
- Security, device-management, archive, and retention requirements
Separate unused seats from unneeded capabilities
An unassigned seat may still be a planned hire or a commitment that cannot immediately be reduced. An assigned license may support a control the user never opens directly, such as device management. Low sign-in activity alone does not establish that an account or subscription is safe to remove.
Compare each role's actual requirements with its assigned plan. Record the reason for a proposed change, the dependencies, and who will validate the result. Avoid assuming that all employees should have the same subscription.
Handle departures as a data and access decision
Before changing a former employee's account, identify who needs their files, mailbox, shared resources, and automated processes. Confirm applicable retention and business requirements with the responsible owner. Microsoft documents different effects for account deletion and license removal; the appropriate sequence depends on the services involved.
Preserving business data and blocking a former employee's access are separate tasks. Agree on both. Do not delete an account simply because it is absent from the current employee roster.
Make a small, verifiable change plan
For each approved change, write down the current state, intended state, expected billing effect, and validation steps. Use a limited first batch when changes affect several people. Check email, file access, required applications, and relevant management controls afterward.
Finish with a dated inventory and a list of unresolved questions. Schedule another review around hiring, departures, renewals, or major platform changes. SyncrionIT can investigate the tenant and document recommendations.
