Exchange 2010 get deleted mailbox
We have last month deleted a user account from AD which has obviously resulted in the deletion of the mailbox. I would normally go into disconnected mailbox and re-connect it to a temporary account etc.
Anyway the disconnected mailbox retention has passed so my question: how do I know which database the mailbox was in so that I can restore a backup of the database then restore the mailbox. Just to clarify the restore of the database and mailbox I am fine with, I just need to know how to identify the database when no user acct exists?
