Dive deep into the architecture of Exchange Web Services—and master the intricacies for accessing data with the new, unifying API. Exchange Web Services offers new functionality, replacing old, disparate APIs. Written by members of the Microsoft Exchange Server 2007 and Exchange Web Services product teams at Microsoft, this practical guide introduces developers to Exchange Web Services. It includes comprehensive, in-depth coverage of the architecture and key features, including messaging, folders, calendaring, tasks, notifications, searching, availability, and autodiscovery. Developers who are moving applications using previous APIs to Exchange Web Services will learn how to determine the correct Web services constructs—and the implications of those decisions. In addition, developers writing new software will develop a well-grounded understanding of the methods available and how to structure interaction with Exchange Server 2007 for maximum benefit and performance. This book assumes only knowledge of how to write HTTP requests, but it provides proxy examples in Microsoft Visual C#®.
