2.2.2.2.3 PidLidDistributionListChecksum Property
Type: PtypInteger32 ([MS-OXCDATA] section 2.11.1)
The PidLidDistributionListChecksum property ([MS-OXPROPS] section 2.95) specifies the 32-bit cyclic redundancy check (CRC) polynomial checksum, as specified in [ISO/IEC8802-3], calculated on the value of the PidLidDistributionListMembers property (section 2.2.2.2.1), as specified in section 3.1.5.11.
The value of this property can be used to detect when the PidLidDistributionListMembers property was updated without updating the other Personal Distribution List Member properties (by computing the CRC on the existing value of the PidLidDistributionListMembers property and comparing it with the value of the PidLidDistributionListChecksum property). The server does not set or update this property.
