2.2.1.13 RopWritePerUserInformation ROP
The RopWritePerUserInformation ROP ([MS-OXCROPS] section 2.2.3.13) is used to establish the set of change numbers of messages the user has read in a specific public folder.
When this ROP is issued against a private mailbox logon, data for the public folder is saved. When this ROP is issued against a public folders logon, the current per-user read/unread data for the public folder is established. The client can use this ROP in conjunction with RopReadPerUserInformation, which is specified in section 2.2.1.12, to synchronize per-user read/unread data for a public folder.
The complete syntax of the ROP request and response buffers for this ROP is specified in [MS-OXCROPS]. This section specifies the syntax and semantics of various fields that are not fully specified in [MS-OXCROPS].
