MAPI Properties

MAPI Property: PR_ORIGINATOR_DELIVERY_REPORT_REQUESTED
Description: Contains TRUE if a message sender requests a delivery report for a particular recipient from the messaging system before the message is placed in the message store.
Property ID: $0023
Property type: PT_BOOLEAN
Area: MIME
Remarks:
 This property is used to direct the messaging system in handling delivered messages. In this case, the message must also furnish the PR_ORIGINATOR_NON_DELIVERY_REPORT_REQUESTED (PidTagOriginatorNonDeliveryReportRequested) property set to FALSE.

Setting the PR_ORIGINATOR_DELIVERY_REPORT_REQUESTED property on a message is a way to request delivery status reports for all recipients.
