Delete a user in Office 365
Before you delete a user's Office 365 account, we recommend you save the user's email and OneDrive data, and take other steps to protect your business. See Remove a former employee from Office 365.
After you delete a user's account, you have 30 days to restore the account before the user's data is permanently deleted.
