3.3.5.7.2 Sending a RopTellVersion ROP Request

Clients MUST pass the server version exactly as it was obtained either from the EcDoConnectEx method response, as specified in [MS-OXCRPC], or from the X-ServerApplication header of the Connect request type response, as specified in [MS-OXCMAPIHTTP]. For more details about the only application scenario for this ROP, server-to-client-to-server upload, see section 3.3.4.2.1.

If the client sends the RopTellVersion ROP (section 2.2.3.1.1.6), the request MUST be sent before the first RopFastTransferSourceGetBuffer (section 2.2.3.1.1.5) or RopFastTransferDestinationPutBuffer ROP (section 2.2.3.1.2.2).
