3.3.5.8.12 Sending a RopGetLocalReplicaIds ROP Request

Clients SHOULD NOT allocate another batch of IDs until the one they allocated before is used up. Allocating IDs in batches of moderate size, between 0x00000200 and 0x10000, is recommended.

The client can reconstruct all allocated GID structures ([MS-OXCDATA] section 2.2.1.3) by combining the returned REPLGUID structure with any GLOBCNT structure values, as specified in section 2.2.2.5, from the [GlobalCount, GlobalCount + IdCount – 1] range.

The client SHOULD use the obtained IDs whenever creating new folders or new messages in any folder within its local replica. For more details about how clients can assign identifiers to objects created in a local replica, see section 3.3.5.2.
