When a user leaves your organization, you may want to delete their user account. This will block them from using the account to access Office 365. And, it frees the Office 365 license so you can assign it to someone else.
Tip: You can re-assign a license without deleting the related account. To learn more, see Assign or remove a license
Delete an account for one or more users
You must be an Office 365 admin to perform these steps.
Sign in to Office 365 with your work or school account.
Go to the Office 365 admin center.
Go to Users > Active Users.
Choose the names of the users that you want to delete, and then select Delete or Delete user .
Your screen might look like either of the following screenshots:
On the confirmation page, select Delete.
The account is now inactive.
After an account is deleted, the user's data is stored for 30 days. If you restore the work or school account within 30 days, the user account and all associated data are restored.
If your organization synchronizes user accounts to Office 365 from a local Active Directory environment, you must delete and restore those user accounts in your local Active Directory service. You can’t delete or restore them in Office 365.
For more information about synchronizing user accounts to Active Directory, see Activate synced users.
