3.2.4.1.2 Generating the Junk Email Move Stamp

If there is no value at zero-based index 5 of the PidTagAdditionalRenEntryIds property (section 2.2.3.1) of the Inbox folder, the client MUST generate an arbitrary PtypInteger32 value ([MS-OXCDATA] section 2.11.1) and store it as an unsigned PtypInteger32 to the zero-based index 5 of the PidTagAdditionalRenEntryIds property of the Inbox folder. For security details, see section 5.1.

The client MUST set the value of the PidNameExchangeJunkEmailMoveStamp (section 2.2.1.2) to the PtypInteger32 value that is stored in the zero-based index 5 of the PidTagAdditionalRenEntryIds property of the Inbox folder.
