Quick overview: Had Exchange 5.5 on a single server environment. Moved everything over to Exchange 2003 and was successful. Installed a new DLT drive, and Veritas worked great - did a test backup with all data, Exchange mailstore and Exchange mailboxes on Monday night.
Tuesday's night backup failed: Unable to attach to \\server\Microsoft Exchange Mailboxes and Public Folders.
Nothing changed - seriously since the night before.
I look at the Job and I cannot even see the Microsoft Mailbox checkbox - only the Mailstore.
Thanks for your help - as always, long live the forums!
