I have a client running Exchange 203 SP1 (aka Version 6.5) on Windows Small Business Server 2003 SP1. Before I upgrade them to SP2, I wanted to ensure that they have a reliable backup - however Symantec BackupExec is telling me that some of the E-Mails in the mailboxes are corrupt. It also says the Mailbox Store is corrupt, which is more troubling. Symantec says to simply disable the reporting of corrupt E-Mails within their program (essentially telling BackupExec to ignore the corruption), but I don't like that solution.
My question: How can I repair the Exchange server and clean up this corruption?
