PidLidUseTnef Property

Type: PtypBoolean ([MS-OXCDATA] section 2.11.1)

The PidLidUseTnef property ([MS-OXPROPS] section 2.347) is set to 0x01 (TRUE) if Transport Neutral Encapsulation Format (TNEF) is included on a message when the message is converted from TNEF to MIME or SMTP format. Otherwise, this property is set to 0x00 (FALSE). If this property is absent, implementers of this protocol MUST NOT include TNEF on the message.

This property is set by either the client or the server, depending on which one is performing the conversion. For information about conversions involving TNEF and MIME, see [MS-OXTNEF] and [MS-OXCMAIL].
