- Marcel Meth, Senior Vice President Internet Strategy, FleetBoston Financial Microsoft Exchange Server addresses the most vital needs of todays corporate software solutions: collaboration, knowledge management, and Web accessibility. The newest version, Exchange 2000, now supports a wide range of APIs to fit the diverse requirements of enterprise developers, including WebDAV, ADO 2.5, ExOLEDB, CDO, and, of course, MAPI. As a result, it is far more flexible, but more complex, than earlier versions. A convenient and comprehensive tutorial and reference, Developing Applications with Exchange 2000 steers you through the many new development options. It provides a programmer-based overview of Exchange 2000, shows you how to build various kinds of applications using these APIs, reveals pitfalls to avoid, and offers experience-based tips for success. In particular, this book focuses on Exchange 2000s newly designed Web Storage System and the many ways it can now be accessed. Specific topics include: *WebDAV *Creating custom Web forms with Outlook Web Access *Outlook Object Model (OOM) and the digital dashboard *Accessing Web Store with ADO 2.5 *ExOLEDB *Making remote calls using DCOM *Using XML to set Access Control Lists *Exchange store events *Using CDO 1.21 and CDO 3.0 for messaging, calendars, contacts, workflow, and exchange management *XML and Exchange 2000 *Accessing WebStore with ExIFS In addition, Developing Applications with Exchange 2000 includes a convenient summary comparing and contrasting the APIs and object models, including development scenarios highlighting recommended usage. Two applications, along with smaller code examples, demonstrate Exchange 2000 in typical daily operations throughout. With this book as a guide, you will be better able to decide which development approach to Exchange 2000 best serves your needs.
