I have an email in my Outbox that continually crashes Outlook for Mac 2011 with a "rebuild database" error message. Rebuilding the database took days and never completed. If I start Outlook in safe mode (holding the shift key when loading), I can get into Outlook but the moment I hit Send/Receive or switch to the Outbox folder (where the culprit email is sitting), I immediately get the "rebuild database" error message and can either Rebuild or Cancel, the latter exits Outlook.
Is there a way to empty the Outbox folder through the file system without click on the folder in Outlook? Any other solution?
