I am running Exchange 2007 with SP1 on a Windows 2008 server with the Hub Transport, Mailbox and Client Access roles on the single server. We back up the Exchange 2007 server nightly with Backup Exec 11D. Today I created a recovery storage group for one of our mailbox databases. I then restored the mailbox database from a backup tape to the recovery storage group successfully. I have run into problems however when trying to restore(merge) a mailbox from the recovery storage group into the production storage group. The error I am receiving is "Error restoring the mailbox (/O=GUIDE DOGS FOR THE BLIND/OU=GDB/CN=RECIPIENTS/CN=SSMITH). Error message is: Error was found for Steve Smith (email@example.com) because: Error occurred in the step: Moving messages. This mailbox exceeded the maximum number of corrupted items specified for this move mailbox operation., error code: -1056749110. This happens for any mailbox I attempt to merge. Has anyone ever seen this and know of a fix?
