The Id method is received by the server in an RPC_REQUEST packet. In response, the server MUST return the represented Message.Identifier.

 [propget] HRESULT Id(
   [out, retval] VARIANT* pvarMsgId
 );

pvarMsgId: A pointer to a VARIANT that contains a 20-byte array (VT_ARRAY | VT_UI1) that contains the unique message identifier.

Return Values: The method MUST return S_OK (0x00000000) on success or an implementation-specific error HRESULT on failure.

  • Set the pvarMsgId output parameter to the value of the represented Message.Identifier.
