TNEF
Transport-Neutral Encapsulation format. A MAPI-defined format that encapsulates MAPI message properties inside a single binary stream. To preserve MAPI properties, a sending application can encode a MAPI message into a TNEF stream and send the stream to a receiving application. The receiving application can use MAPI to decode the stream and reconstruct the original MAPI message.
