When you use Collaborative Data Objects (CDO) to create meetings programmatically in Microsoft Exchange Server 2003, meetings are unexpectedly moved one hour ahead in the last week of October.
This problem occurs when all the following conditions are true:
- Users in your organization use e-mail clients such as Microsoft Outlook Web Access. Alternatively, users use other devices or programs that use CDO to view and to manage their calendars.
- Your organization is configured to a time zone that is represented by Coordinated Universal Time (UTC) time 00:00. (Coordinated Universal Time is also known as Greenwich Mean Time [GMT].)
Note This problem does not affect Exchange if the organization is configured to use a time zone other than a time zone in UTC 00:00.
- The month of October has five Sundays.
Note This problem will occur next in the year 2010.
