Veritas: Access is denied error to emails that don't exist!

Exchange 2003
Windows Server 2003 SBS
Veritas Backup Exec 9.1 with SP1

Almost once a week the backup will fail due to some emails being corrupted or infected with a virus, and Backup Exec will give the 'access is denied' error happily.  Normally I will simply open the mailboxes and delete the offending emails.  This time I have done just that but the backup is still fails as the emails appear to still exist according to Backup Exec.  The exact same 'access is denied' error occurs for the same emails, even though I have deleted them.

Heres what I have tried:

- Rebooted the server to clear the information store
- Ran isinteg -s servername -fix -test alltests
- Ran eseutil /d  and /p

It can't be a permission problem and the emails definitely do not exist.  Anyone had this one before?

Exchange has a default retention of 30 days for deleted mailboxes.  During that time, BE cannot back it up because it is in Limbo.

The mailbox backup in BE will fail at the drop of a hat.  If just one SPAM message comes in with a corrupt GIF, it will cause the entire job to fail.

My advice to you is to seperate the backup job for the Information Store from the backup of the mailboxes.  As long as the Information Store is backed up, the mailbox backup is just a redundant copy to make it easier to restore a single message or mailbox.

Once you have these seperated, don't worry if the mailbox backup says failed, just watch the byte count and make sure it stays consistant.

Is there a way to clear the 30 day retention or perhaps reduce it to 1 day?  

So if the job fails due to a corrupt email/attachment the job can still be restored from, despite saying it as failed?

In Exchange System Manager go to Server -> Servername -> First Storage group and right click on your mailbox store and choose properties.

Go to the "Limits" tab to adjust the retention setting.

Yes, you can still restore a job when it has the failed status.

We have found another way around this, Within your job selection, Locate the offending file in the selection list of the job and Uncheck that single item and save the job. Then the following days backup does not fail because of that corrupt email.
