1.5 Prerequisites/Preconditions

This protocol assumes that the client has previously established a Session Context with the server, as specified in [MS-OXCRPC] and [MS-OXCMAPIHTTP]. Once that connection is made, the client is then able to follow the protocol specified in this document to establish a logon session with a private mailbox, or the public folders. After the logon session is established, the client follows the protocol specified in this document to perform various operations on the user mailbox and make discoveries about where public folder content is located.

All ROPs described in [MS-OXCROPS], except the RopLogon ROP (section, are performed with the assumption that the client has successfully logged on to the server using RopLogon ROP.
