MAPI Properties
This section provides detailed information about the Windows Mobile-based Messaging API (MAPI) properties described in the following table.
**Note **Unlike members of COM variant arrays, every member in a MAPI multivalued property array is of the same type. Conversation ID is not implemented. (Message grouping by thread is not supported.) There is no provision in Windows Mobile-based MAPI for iterating through an item's properties. Instead, you must retrieve one property at a time.
