Restore a user in Office 365

When you restore a user account within 30 days after deleting it, the account and all associated data are restored. The user can sign in with the same work or school account. Their mailbox will be fully restored. To find out how much time remains before a specific user account can no longer be restored, contact us.

Restore a user that has a user name conflict

A user name conflict occurs when you delete a user account, create a new user account with the same user name (either for the same user or another user with a similar name), and later try to restore the deleted account.

To fix this, replace the active user account with the one that you are restoring. Or, assign a different user name to the account that you are restoring so that there aren't two accounts with the same user name. Here are the steps.

  1. Go to the Go to the Office 365 admin center..
  1. In the Admin center, go to Users > Deleted users.

    Choose Users > Deleted users.

  2. On the Deleted users page, choose the names of the users that you want to restore, and then select Restore.

    Note

    If two or more users fail to be restored, an error message advises you that the restore operation failed for some users. View the log to see which users were not restored, and then restore the failed accounts one at a time.

  3. Follow the prompts to set the password.

  4. Click Restore.

  5. A message pops up that says there was a problem restoring the account. Do one of the following:

  • Cancel the restore and rename the current active user. Then attempt the restore again.

  • OR, type a new primary email address for the user and click Restore.

  1. Review the results, and then select Close.
