The PR_SENT_REPRESENTING_SEARCH_KEY property is one of the address properties for the messaging user being represented by the sender. When a client application sends a message on behalf of another client, it should set all the represented sender properties to the values for that client. A messaging user sending on its own behalf typically leaves the represented sender properties unset.
The outgoing transport provider must always leave PR_SENT_REPRESENTING_SEARCH_KEY unchanged if it has been set by the sending client. If it is unset, the transport provider should set it to PR_SENDER_SEARCH_KEY on the outbound copy of the message, and leave it unset on the local copy.
