The CDO libraries now support both server and client-based applications, providing developers with a common set of programming interfaces. In addition, CDO now provides a stand-alone setup, allowing developers to install CDO on servers running Microsoft Internet Information Server that do not have Microsoft Exchange Server installed.
For more information, see the Cdo.hlp file located in the Eng\Server\Setup\I386\Bin directory on the SP1 compact disc. The document is available only in English for all language versions of SP1.
