The MAPI-MIME Conversion API allows mail providers to convert between MIME objects and MAPI messages. It provides constant definitions, class identifiers, and interface identifiers as shown in MAPI Constants. Mail providers must cocreate an instance of IConverterSession by calling the CoCreateInstance function.
