Microsoft producets afected by the DST changes:

• Microsoft Windows
• Microsoft Windows SharePoint Services
• Microsoft Exchange Server
• Microsoft Office Outlook
• Microsoft Office Live Meeting
• Microsoft Dynamics CRM
• Microsoft SQL Server Notification Services
• Microsoft Entourage

All users of Microsoft products affected by the time change should give extra attention to meetings and appointments scheduled between March 11, 2007 to April 1, 2007 and October 28, 2007 to November 4, 2007, referred to here as the "extended DST period." (In this article, the terms "meetings" and "appointments" will be used interchangeably.) Users should view any appointments that fall into these date ranges as suspect until they communicate with all meeting invitees to make sure that the item shows up correctly on everyone's calendar both internally and externally. To minimize confusion during the affected date ranges:

• Include the time of the meeting in the e-mail request so that invitees can double check the correct meeting time (such as, "Project brainstorming - 11:00 A.M. Central Time").

• Exercise caution with the appointments and meetings in the extended DST period. When in doubt, verify the correct time with the organizer.

• Consider printing out your weekly calendars during the extended DST period prior to applying the Windows patch containing the updated time zone definitions and running the Outlook Time Zone Update tool so that you can keep track of which meetings were scheduled before and after you run the tool.
