2.2.2.26 PidTagReadReceiptEntryId Property

Type: PtypBinary ([MS-OXCDATA] section 2.11.1)

The PidTagReadReceiptEntryId property ([MS-OXPROPS] section 2.882) contains an address book EntryID, as specified in [MS-OXCDATA] section 2.2.5.2, that represents the user to whom a read receipt is directed. This property is only used and validated if the PidTagReadReceiptRequested property (section 2.2.1.29) is set to 0x01. This property can be absent, in which case, the value of the PidTagReportEntryId property (section 2.2.2.19) is used as an alternative value. If neither property is present, the value of the PidTagSenderEntryId property (section 2.2.1.50) is used to identify the user who receives the read receipt.
