We have a Windows 2008r2 domain and use Exchange 2007. A user account was accidently deleted but no one has touched the Exchange server yet. I see an entry for the account on exchange but with no AD account associated with it, I just get errors if I click it on. I already spoke with our backup provider and apparently there is no way to restore a single AD account. Is there a way to rebuild a new AD account and associate it with the email store that exists from the old AD account?? Or any other way out of this?
