Update : What’s New in Exchange 2010 Web Services


Exchange 2010 introduces the following important changes that might affect your Web services–based applications:

  • Several new features have been added to Exchange Web Services (EWS), including operations related to the following: user configuration, mail tips, message tracking, calendar and contact sharing, room availability, time zones, service configuration, and Unified Messaging.
  • A new SOAP-based Autodiscover service has been introduced as an alternative to using the “plain old XML” (POX) Autodiscover service.
  • Exchange Web Services (EWS) has been updated to include Unified Messaging functionality. You no longer have to use the separate Unified Messaging Web service (nor do we [MS]recommend this).
