2.2.13 RopGetNamesFromPropertyIds ROP
The RopGetNamesFromPropertyIds ROP ([MS-OXCROPS] section 2.2.8.2) maps concrete property IDs to abstract, client-defined named properties. This operation is valid on Message objects, Attachment objects, Folder objects, and Logon objects. Property IDs for named properties are identified by having their most significant bit set (0x8000). The client can request to map non-named property IDs (IDs with the most significant bit unset) into names.
The PS_MAPI namespace is used for mapping non-named property IDs into names.
The complete syntax of the ROP request buffer and the ROP response buffer is specified in [MS-OXCROPS]. This section specifies the syntax and semantics of various fields that are not fully specified in [MS-OXCROPS].
