2.2.2.2.4 PidLidDistributionListStream Property

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

The PidLidDistributionListStream property ([MS-OXPROPS] section 2.99) specifies the list of EntryIDs and one-off EntryIDs corresponding to the members of the personal distribution list. Members of the personal distribution list can be other personal distribution lists, electronic addresses contained in a contact, GAL members, or one-off email addresses. The format of each EntryID MUST be as specified in section 2.2.2.2.1, and the format for each one-off EntryID MUST be as specified in section 2.2.2.2.2.

The PidLidDistributionListStream property is intended to allow a distribution list to grow past the size limits of the PidLidDistributionListMembers property (section 2.2.2.2.1) and the PidLidDistributionListOneOffMembers property (section 2.2.2.2.2). This property SHOULD<16> be used if the size of either PidLidDistributionListMembers or PidLidDistributionListOneOffMembers would be greater than 15,000 bytes. If this property is set, the PidLidDistributionListMembers, PidLidDistributionListOneOffMembers, and PidLidDistributionListChecksum (section 2.2.2.2.3) properties SHOULD<17> be ignored.

The following diagram specifies the buffer format of the PidLidDistributionListStream property.

StreamVersion (2 bytes):  A 16-bit value that specifies the version of the stream. This field MUST be set to 0x0001.

Reserved (2 bytes):  This field MUST be set to zero when sent and MUST be ignored when received.

BuildVersion (4 bytes):  A 32-bit value that specifies the build version of the stream. The value of this field is the value of the MajorVersion field of the PidLidBusinessCardDisplayDefinition property (section 2.2.1.7.1) multiplied by 10,000. The value of the MinorVersion field of the PidLidBusinessCardDisplayDefinition property is then added to the result.

DistListStreamFlags (4 bytes):  A 32-bit value that contains bits that indicate overall behavior of the personal distribution list. The following table specifies the valid flags.

DistListStreamFlags byte table. Bit 0 is Always use stream. Bits 1 through 31 are Reserved.

Figure 3: DistListStreamFlags byte table

If the Always Use Stream bit is set, a client MUST save the personal distribution list members in the stream, even if the members would normally fit in the PidLidDistributionListMembers and PidLidDistributionListOneOffMembers properties.

When modifying the personal distribution list, a client MUST preserve any data in the Reserved portion of this field. When creating a new personal distribution list, this value MUST set the reserved bits to 0.

CountOfEntries (4 bytes):  An integer that specifies the number of DistListMemberInfo structures, as specified in section 2.2.2.2.4.1, in the DistListMemberInfoArray field.

TotalEntryIDSize (4 bytes):  An integer that specifies the sum of the sizes (in bytes) of the EntryIDs stored in each DistListMemberInfo structure.

TotalOneOffSize (4 bytes):  An integer that specifies the sum of the sizes (in bytes) of the one-off EntryIDs stored in each DistListMemberInfo structure.

TotalExtraSize (4 bytes):  Not used. This field MUST be set to 0x00000000.

DistListMemberInfoArray (variable):  An array of DistListMemberInfo structures (section 2.2.2.2.4.1), each of which contains information about one member of the personal distribution list.

Terminator1 (4 bytes):  Not used. This field MUST be set to 0x00000000.

Terminator2 (4 bytes):  Not used. This field MUST be set to 0x00000000.
