Sending a RopCreateMessage ROP Request

After calling the RopCreateMessage ROP ([MS-OXCROPS] section, the client sends a RopSaveChangesMessage ROP request ([MS-OXCROPS] section to commit the new Message object and uses the opened Message object in subsequent ROPs. It MUST eventually send a RopRelease ROP request ([MS-OXCROPS] section on the Message object and, after doing so, MUST NOT use the Message object for any subsequent ROPs.
