We're running Symantec Backup Exec 12.5 to backup a Windows SBS 2008 server.
Recently we started receving the following error in Backup Exec:
Final error: 0xe000febd - The Logon account you specified must correspond to a unique mailbox.
For example "admin" isn't unique if there is an "administrator" account.
Final error category: Resource Errors
After searching Symantec articles we found that this usually indicates a conflict of the mailbox name that's used to run the backup with another mailbox. Or that one of the following conditions are not met: Account should be unhidden from GAL, should have active mailbox, should be domain admin, should have full rights on exchange
We've checked all of this and it all seems fine, so I'm not sure what's causing the error.
Backups appear to be completing mostly, but this error indicates that Exchange data isn't being backed up.
