Dear Aspose Team,
MapiMessage mapi = MapiMessage.FromFile(“98991B4D724051A7927667C8D2529FB2.MSG”);
MapiProperty prop = mapi.Properties[MapiPropertyTag.PR_RECEIVED_BY_NAME_W];
String data = prop.GetString();
Please test the shared sample code at your end as per your convenience. We’ll discuss the possible availability of these as properties in MapiMessage and MailMessage classes with our Product team and share the feedback here with you.
