1.4 Relationship to Other Protocols
A client that implements this protocol can use the Autodiscover Publishing and Lookup SOAP-Based Web Service Protocol, as described in [MS-OXWSADISC], or the Autodiscover Publishing and Lookup Protocol, as described in [MS-OXDSCLI], to identify the target endpoint (4) to use for each operation.
This protocol uses the SOAP Protocol, as described in [SOAP1.1], to specify the structure information exchanged between the client and server. This protocol uses the XML Protocol, as described in [XMLSCHEMA1] and [XMLSCHEMA2], to describe the message content sent to and from the server.
When requests are made by using the Core Items Web Service Protocol [MS-OXWSCORE], the task information that is returned by the Tasks Web Service Protocol will be used if the targets of the requests are task items.
This protocol can use the Task item identifier returned by the Mailbox Search Web Service Protocol, as described in [MS-OXWSSRCH], to manipulate the Task item.
For conceptual background information and overviews of the relationships and interactions between this and other protocols, see [MS-OXPROTO].
