What's the number of times the letter "." appears in:
Q: Incorrect "Mailbox Store" in Active Directory I recently had to restore our primary domain controller from a backup, but the backup was taken before a mailbox was moved (from mail1 to mail2). The user now has the problem that they cannot access their email. This appears to be because Outlook is looking for the emails on mail1.domain.com, whereas the actual emails are on mail2.domain.com.
In AD, the users "Mailbox Store" attribute is set to "MAIL1/First Storage Group/Mailbox Store (MAIL1)".
In event viewer on MAIl1 (which is also our PDC), the following event is logged :
Event Type: Error
Event Source:   MSExchangeIS Mailbox Store

Description:
Failed to create the mailbox of

How can I tell AD where the mailbox is correctly located?
