18.104.22.168.8 PidTagArchiveDate Property
Type: PtypTime ([MS-OXCDATA] section 2.11.1)
The PidTagArchiveDate property ([MS-OXPROPS] section 2.570) specifies the date, in UTC, after which a Message object is archived by the server. The PidTagArchiveDate property can be present on only Message objects, not on folders, and can be set by both client and server. If the PidTagArchiveDate property is not present, the Message object is never archived by the server.
The value of the PidTagArchiveDate property is calculated from the values of other properties as follows:
PidTagArchiveDate = start date + PidTagArchivePeriod (section 22.214.171.124.7)
The start date is obtained from the last eight bytes of the PidTagStartDateEtc property (section 126.96.36.199.4).
