When outlook sends a custom form, it has an attachment called winmail.dat. That attachment contains custom mapi properties encoded as TNEF, that the custom form will use. I want to send an email using the winsock control (which I have already done) But I want to attach this TNEF encoded attachment. Does any one know of a way to encode/decode TNEF?
Ill keep my fingers crossed.
Try the following link :

The ITnef interface provides the following methods:
