MAPI Property:
PR_SENDER_ADDRTYPE, PR_SENDER_ADDRTYPE_A, PR_SENDER_ADDRTYPE_W
Description:
Contains the message sender's e-mail address type.
Property ID
:
$0C1E
Property type:
PT_UNICODE, PT_STRING8
Area:
Address
Remarks:
These properties are examples of the address properties for the message sender. It must be set by the outgoing transport provider, which should never propagate any previously existing values.
If no transport provider has supplied any sender address properties, the MAPI spooler attempts to fill them in by calling the IMAPISession::QueryIdentity method for an entry identifier. If no entry identifiers have been provided, the MAPI spooler stores "Unknown" in all the sender address properties of type PT_TSTRING.
