Pete,
The MSMAPI.MAPISession and MSMAPI.MAPIMessages components work great with OE. You have to set OE as the default Simple MAPI client. You should also get IE4.01 there were some significant bugs in file attachment handling in the IE4.0 version. The \samples\solution has a good start showing you how. Visual FoxPro 3 Unleashed has a well written section on MAPI.
