This protocol uses SOAP, as described in [SOAP1.1], to specify the structure information that is exchanged between the client and the server. This protocol uses the XML schema, as described in [XMLSCHEMA1] and [XMLSCHEMA2], to describe the message content that is sent to and from the server.
The Nonindexable Item Web Service Protocol, as described in [MS-OXWSGNI], uses the mailbox search and mailbox hold information provided by this protocol.
