I have an Exchange user who cannot view messages in a particular mailbox folder in the "On My Computer" bucket. The messages can still be found on her computer using Spotlight; however, they are not viewable from within the Outlook application. I have rebuilt her Outlook database with no luck. I have checked for peculiar rules and don't see any listed. 

This problem occurred after a migration from a G5 to an iMac using Migration Assistant. The problem was recently reported, but the migration occurred about a month ago. I'm thinking that migration could have spawned an issue with DB integrity. The good news is that I might still have access to her old G5. If I were to export an OLM from her old computer and import it into Outlook on her iMac, do you think it would resolve the issue? Any other ideas besides trashing preferences?
