Here's the code  I use in XL 2003 with Outlook 2003. This is a "one button"
solution for me . . . it creates a subject, body  text, email addresses,
etc., from information in the workbook. I usually display the email and
then send  to avoid the security warnings and to provide an opportunity to
add any changes to the body text. 99% of the time, I can just click send
and be done.
