1.3.1 Server Objects

A Server object refers to an object created during the processing of specific ROPs. Once created, a Server object can then be used as a parameter for other ROPs until it is released. A Server object is typically a view of data on the server, such as a Folder object or a Message object, but it could also be an object used to control synchronization or change notifications. 

A Server object is identified by a Server object handle, a 32-bit handle value. This handle is assigned by the server when the Server object is created. A client uses a Server object handle to specify a Server object to be used as input for a ROP request.
