ITnef
: IUnknown
The ITnef
interface provides methods for encapsulating those MAPI properties not
supported by a messaging system into binary streams that can accompany messages
through transport provider handling and through gateways. The format used for
this encapsulation is Transport-Neutral Encapsulation Format (TNEF). The target
transport provider can then, on receiving a message including TNEF-encapsulated
properties, decode the encapsulation to retrieve all the properties of the
original message.
