Calendaring

Microsoft® Exchange Server 2003 includes rich calendaring features that you can use to build calendaring applications. Collaboration Data Objects (CDO) provides the logic necessary to create applications that incorporate appointments, meetings, messages, and other calendaring items. The topics in this section describe how to use CDO to develop custom calendaring solutions.
