I have Backup Exec 2010 installed and I have a valid Exchange agent. I successfully did a disk to disk backup from my Exchange server to my standalone Backup Exec 2010 box. No tape involved. No clustering ... just a stand alone Exchange 2007 box.
Everything completed successfully and it looks like I have a good backup.
I went to do a fake restore just so I could look at the contents of the backup and I could see that two mailboxes were missing from the list in the storage group. They just happen top be the only two Domain Admins on the network.
I have read about missing mailboxes before, I wonder if it is a permission issue on the mailbox. What should the user permissions look like on the mailbox to ensure a proper backup? We have messed with our permissions a lot and I am wondering if that is the issue.
