Solution 1Recommended

Verify and Update License Status in the Microsoft 365 Admin Center

Check if the deleted user's license was canceled instead of just unassigned, and purchase a new license if necessary.

When a user is deleted, their license is supposed to return to your organization's pool of available licenses. However, if the license was fully canceled or unsubscribed during the deletion process, it is permanently removed from your subscription. In this case, you will need to purchase a new license to assign to the new employee.

1
Access the Microsoft 365 admin center

Navigate to admin.microsoft.com and log in with your administrator credentials.

2
Navigate to the Billing section

In the left-hand navigation menu, click on 'Billing' and then select 'Your products' or 'Licenses' to view your current subscriptions.

3
Review available licenses

Locate your Microsoft 365 Business Premium subscription and check the 'Available licenses' count. Compare it to the total number of licenses you expect to have.

4
Purchase a new license if canceled

If the available license count is zero or lower than expected, the license was likely canceled. Click on the subscription, select 'Buy licenses', and add the required number of licenses for your new employees.

Canceled vs. Unassigned Licenses: Unassigning a license removes it from a specific user but keeps it active and billed in your tenant. Canceling a license removes it entirely from your billing account, requiring a repurchase.

Frequently Asked Questions

How do I unassign a Microsoft 365 license without deleting the user account?

In the Microsoft 365 admin center, go to 'Users' > 'Active users'. Select the user, click on the 'Licenses and apps' tab, uncheck the specific license you want to remove, and click 'Save changes'.

Why am I still being billed for a deleted user's Microsoft 365 license?

If you delete a user but do not manually reduce your total license count in the 'Billing' > 'Your products' section, Microsoft will continue to charge you for that license so it remains available for a future employee.

How long is a deleted user's data retained in Microsoft 365?

When a user is deleted and their license is removed, their Microsoft 365 data, such as emails and OneDrive files, is typically retained for 30 days before being permanently deleted from the servers.
