David, thank you for your reply. Just one more thing, though...how in the heck do I check that its the Default Simple MAPI client? Somewhere in the registry, or something through Control Panel? I am lost...ExpressIT doesn't seem to have a configuration option such as "Make ExpressIT the default Simple MAPI client".

>>I am using the MAPI class from the Files section to programmatically send mail, and it is working fine on one of our computers, but is behaving differently on another PC. Both PCs are Windows NT 4.0 machines with ExpressIT! as the e-mail client (this is a Novell shop). Outlook 97 is also installed on these PCs, but is not used for mail sending.

>>One of the PCs works as I expect. It sends the mail using the ExpressIT system. On the other PC, when the app tries to send mail, the Outlook 97 Select Profile dialog appears, and the mail sending fails (which generates all sorts of OLE Dispatch errors in VFP).

>>What do I need to change in the registry so that the PC uses ExpressIT for MAPI instead of Outlook?
