Can you move those messages from the Outbox to the Drafts folder?
If one is 'stuck' and can't be deleted, try the Microsoft fix:

"Messages may be stuck in the Outbox when you use Windows Mail on a
computer that is running Windows Vista"
That page offers two download options. Unless you know for sure
you have 64-bit Vista, use the 32-bit option.
