The PR_ORIGINAL_SENT_REPRESENTING_SEARCH_KEY property is one of the address properties for the original represented sender of a message. It is used in a conversation thread.
A client application sending a message on behalf of another client should set this property to the value of the PR_SENT_REPRESENTING_SEARCH_KEY property at the first submission of the message. Once set, it should never be changed.
