Error Message can't send
 

I had to do a clean reinstall and since I put nin my office 2003 my outlook
will not let me send. Error message saysunable to send test message. Verify
e-mail address field. The address field is correct. I tryed uninstalling
and reinstalling but was not able to totally clean the program out so my info
is still there. I could use a suggedtion as to what to do.
