You can change the MailItem.BodyFormat property on the fly, but to change it
for all messages by default you can use code to edit the setting in the
registry (which may require an Outlook restart to take effect).

I have my VBA applications that access MS Outlook 2003 to send emails.
However I would want to turn off the option "Use MS Office 2003 to edit
e-mail messages"

Can someone help me with the VBA code to do the same?

Thanks
