Making Sure the Message Gets There
Making Sure the Message Gets There
The Message object contains two properties that can direct the underlying MAPI system to report successful receipt of the message: DeliveryReceipt and ReadReceipt.
When you set these properties to True and send the message, the underlying MAPI system automatically tracks the message for you. When you set the DeliveryReceipt property, the MAPI system automatically generates a message to the sender reporting when the recipient receives the message. When you set the ReadReceipt property, the MAPI system automatically generates a message to the sender reporting when the recipient reads the message.
Delivery and read notification may not be supported by all messaging systems.
