Outlook for Mac 2011 - how to delete buggy email in outbox that crashes Outlook 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?

Thanks.
Can you delete the message in the outbox from webmail?  If it is not in webmail then it's on the outlook end of things.  If that is the case I would remove the entire profile in outlook and re-enter the e-mail accounts and let it build all over again rather than trying to just rebuild the database.
