Exchange Web Service: Web Services Message cycle

Exchange Web Services Message cycle 

  • When a client application requests information from the Exchange store, an XML request message that complies with the SOAP standard is created and sent to the Exchange server.
  • When the Microsoft Exchange server receives the request, it verifies the credentials that are provided by the client and automatically parses the XML for the requested data.
  • The server then builds a SOAP response that contains XML data that represents the requested strongly typed objects and their properties.
  • The XML data is sent back to the client application in an HTTP response.
  • The client application then deserializes the XML and uses the data to reform the strongly typed objects.
