3.3.5.13 Sending the MetaTagIdsetGiven ICS State Property

The property tag for this property suggests that it is of type PtypInteger32 ([MS-OXCDATA] section 2.11.1), but the data MUST be handled as PtypBinary ([MS-OXCDATA] section 2.11.1) data by clients. Clients SHOULD send the MetaTagIdsetGiven property (section 2.2.1.1.1) with a property tag that defines it as PtypInteger32.

This property is not downloaded back to the client in the final ICS state obtained for them through the RopSynchronizationGetTransferState ROP (section 2.2.3.2.3.1). Clients SHOULD remove this property before uploading the initial ICS state on synchronization upload contexts and clients MUST merge this property back in when receiving the final ICS state from the server. Clients MUST add IDs of messaging objects created in or originating from a local replica to this property by using a process called checkpointing, as specified in section 3.3.5.6.
