Here are the development features that are de-emphasized…

There are legacy Exchange features that are now being deemphasized in Exchange 2007:

• Public folders - Free/busy calendaring functionality is provided by the Availability service. If you need additional functionality, migrate to SharePoint Portal Server or a similar product.
• Proxy address generators - Use the Exchange Management Shell.
• CDO 1.2.1 - This functionality is provided by the Exchange Web Services.
• MAPI32 - This functionality is provided by the Exchange Web Services.
• CDOEX (CDO 3.0) - This functionality is provided by the Exchange Web Services.
• Exchange WebDAV extensions - This functionality is provided by the Exchange Web Services.
• ExOLEDB - This functionality is provided by the Exchange Web Services.
• Store events - This functionality is provided by the Notification Web service.
• Streaming backup APIs.
• Exchange 2003 Virus Scanning Application Programming Interface (VSAPI)."

Keep in mind that de-emphasized features will still be supported to work on or against Exchange 2007 but we will strongly discourage you from writing new solutions that use these APIs.
