Migrating from CDOEX
Topic Last Modified: 2007-06-05
Collaboration Data Objects for Exchange 2000 Server (CDOEX) is used to develop messaging applications. These applications use messaging to send and process the following:
- Calendar and contact information
- Access to mailboxes and public folders
CDOEX is de-emphasized in Microsoft Exchange 2007. We recommend that you use Exchange Web Services to develop new messaging applications, and migrate existing applications to Exchange Web Services when you can.
Migrating to Exchange Web Services
Exchange Web Services provides the same access to the Exchange store that CDOEX provides. Unlike those built by using CDOEX, client applications built by using Exchange Web Services can be run on a local or remote computer.
Note
CDOEX can only be run on a computer on which Microsoft Exchange is installed.
You will have to redesign applications that were created by using CDOEX to use Exchange Web Services. Consider redesigning custom applications as early as possible, as future versions of Microsoft Exchange may not contain the CDOEX API.
