Has anyone been able to clear the OUTBOX?

I tried the WMTuil with no success. It only presents File Statistics, Clean
Blank Files, Change and Close. The other options are greyed out I continue
getting One or more messages in your Outbox do not have a valid account
specified. Would you like to use your default account to send these
messages? Yes or NO and no matter which one I select, it wil not clear.
Message could not be displayed
Windows Mail encountered an unexpected problem while displaying this

However, I am using Vista.
