The Simple Messaging Application Programming Interface (MAPI) MAPIReadMail function won't respond with a return-receipt message when it is reading return-receipt requested mail messages. It is the responsibility of the Mail client application, such as Microsoft Mail for Windows, to return a receipt to the sender.

You can use Simple MAPI to find out if a return-receipt request has been sent. To do so, use the MAPIReadMail function to check the flags parameter of MAPIMessage. If the flags value is equal to or greater than 2, but not 5, the MAPI_RECEIPT_REQUESTED flag was set. After you determine that a return-receipt request message was sent, you can send a custom receipt message back to the sender.

Microsoft Mail for Windows will recognize a MAPI return-receipt request and send back a return-receipt message to the sender.
