2.2.1.43 PidTagReplyRecipientEntries Property
Type: PtypBinary ([MS-OXCDATA] section 2.11.1)
The PidTagReplyRecipientEntries property ([MS-OXPROPS] section 2.916) identifies a FlatEntryList structured array of address book EntryIDs for recipients (2) that will receive a reply. When the PidTagReplyRecipientEntries property and the PidTagReplyRecipientNames property (section 2.2.1.44) are defined, the reply is sent to all the recipients (2) identified by these two properties. If this property is absent, a reply is sent only to the user identified by the PidTagSenderEntryId property (section 2.2.1.50). If present, the property is set to a FlatEntryList structure of recipient (2) EntryIDs, as specified in [MS-OXCDATA] section 2.3.3.
The PidTagReplyRecipientEntries property and the PidTagReplyRecipientNames property MUST be set in a way that they contain the same number of recipients (2) in the same order.
