I deleted a users mailbox in the ECP- AD user was of course also deleted. The recycle bin is not enabled.

Is the only way to recover the user and mailbox with an authoritative restore?

  1. You can't restore the mailbox by restoring the user account. If you don't have a backup of the mailbox then see this link:


  1. You can restore the deleted user account with the ADResore utility from Sysinternals:


  • The ADRestore has been last updated in 2006. Although the article includes support for Windows 2008 R2, I would consider it's usage as a bit risky and double-check if it will work properly in your environment. – Vick Vega Apr 23 '16 at 19:41
  • ADRestore isn't doing anything that you can't do yourself with NTDSUTIL (which isn't deprecated). ADRestore is just simplifying the process. – joeqwerty Apr 23 '16 at 19:53

As far as I am aware apart from pulling the data from a backup you will have to use Authoritative Restore. Definitely interested in seeing i there is an alternative myself.
