2.2.1.1.4 MetaTagCnsetRead ICS State Property

Property ID: 0x67D2

Data type: PtypBinary, 0x0102 ([MS-OXCDATA] section 2.11.1)

The MetaTagCnsetRead property contains a serialization of REPLGUID-based CNSET structures, as specified in section 2.2.2.4. The CN structures, as specified in section 2.2.2.1, in the CNSET track changes to the read state for messages in the current synchronization scope that have been previously communicated to the client and are reflected in its local replica. This property does not track whether messages have been read, it only tracks changes to the read state of a message. For more details about tracking read state changes, see section 3.2.5.6.

The read state of a message is determined by the PidTagMessageFlags property ([MS-OXCMSG] section 2.2.1.6), which contains a bitmask of flags that indicate the origin and current state of the message.
