We upgraded a system from 10d to 11 that is running Windows SBS 2003. Before, we had brick-level and database-level backups scheduled for Exchange. With the upgrade, it seems legacy backups are enabled because the brick-level is still in the selection list.
The organization has a number of disabled accounts, and in order to avoid failing in the past, we've manually de-selected those accounts under the brick-level backup. However, with 11, the database-level/information store backup is failing with 0xe0008488 - access is denied (Access denied to database). I've tested the logon account for the information store - it's fine. It actually appears to back up the information store pretty much in entirety by the amount it processes successfully. It did work for a little while without errors on 11, but I believe started failing when we disabled another account in Active Directory. Any suggestions?
