Outlook 2007 keeps trying to send messages that I can't see?

[DWK]

Since upgrading to office 2007, two of my email services cannot do a send
from Outlook, which is fine cause the third one does. BUT I seem to have 4
phantom messages that I cannot see anywhere that are constantly trying to
send via one of the ones I can't send by anymore. How do I stop this little
annoying wrinkle? And yes I did a full scan for viruses and spyware, etc
using my Trend Micro program.
