MAPI Property: PR_RCVD_REPRESENTING_ENTRYID
Description: Contains the entry identifier for the messaging user who is represented by the receiving user.
Property ID: $0043
Property type: PT_BINARY
Area: Address

Remarks:
This property is one of the address properties for the messaging user who is being represented by the receiving user. It must be set by the incoming transport provider, which is also responsible for authorization or verification of the delegate. If no messaging user is being represented, this property should be set to the entry identifier contained in the PR_RECEIVED_BY_ENTRYID (PidTagReceivedByEntryId) property.
A client application replying to a message received on behalf of another client should copy this property from the received message into the PR_SENT_REPRESENTING_ENTRYID (PidTagSentRepresentingEntryId) property for the reply.
