1.4 Relationship to Other Protocols
This protocol extends the Message and Attachment Object Protocol, as described in [MS-OXCMSG].
Clients that use this protocol rely on the Store Object Protocol, as described in [MS-OXCSTOR], to obtain the ID of the OAB data folder of the local site. The ID is retrieved from the server when it logs on to the public folder by using RopLogon property ([MS-OXCROPS] section 188.8.131.52).
For conceptual background information and overviews of the relationships and interactions between this and other protocols, see [MS-OXPROTO].
