A LongTermID structure is a Global Identifier structure, as specified in section 2.2.1.3, plus a 2-byte Pad field that has the value 0x0000. The total length of the LongTermID structure is 24 bytes.

LongTermID structures can be generated from the Message ID structure, as specified in section 2.2.1.2, or Folder ID structure, as specified in section 2.2.1.1, by using the RopLongTermIdFromId ROP ([MS-OXCROPS] section 2.2.3.8). Message ID structures and Folder ID structures can be generated from their associated LongTermID structures by using the RopIdFromLongTermId ROP ([MS-OXCROPS] section 2.2.3.9).
