How do I cancel messages from my outbox that won't send?

[Coup]

I even asked an IT guy who could not tell me how to remove a message that
started to send and then stopped. It won't delete but yet it slows my mail
process down considerably. Any suggestions?

Click File and check Work Offline. Wait five minutes or close and restart
Outlook. Delete the message. Click File and uncheck Work Offline.

Delete an item stuck in the Outbox folder:
- Load Outlook.
- Put Outlook in offline mode (File -> Work Offline: enable).
- Exit Outlook.
- Load Outlook in its safe mode ("outlook.exe /safe").
- Delete the stuck item in the Outbox folder. If you don't want the
item to move into the Deleted Items folder, use Shift+Del to
permanently delete the item.
- Put Outlook in online mode (File -> Work Offline: disable).
- Restart Outlook in its normal mode.
