I use B&R v8 to backup Active Directory 2008 VM. I was testing restoring a deleted user with Exchange 2010 mailbox. I was able to successfully restore Active Directory user. I see the user as enabled User Mailbox from Exchange Management Console. However, I see identical one under Disconnected Mailbox in Exchange Management Console as disabled mailbox. I couldn't access the OWA using the account. I was getting NDR when attempted sending email to the user. So, I disabled "the enabled Mailbox" for the user in Exchange Management Console. Then, I re-enabled the one under disconnected mailbox by Connecting to restored AD user account. After that, I was able to access OWA and send email to the account. Is this normal precedure to restore AD account & connect to disconnected mailbox?
Ken, normally Veeam Explorer for AD should automatically reconnect the mailbox to the restored user. I recommend contacting technical support to investigate why this didn't happen.
I'm not sure about the mailbox not working correctly. But, I've seen the same issue with a mailbox being restored in our environment after restoring an AD user, where you see it in both places. (this isn't a Veeam issue, or an issue at all really)
