As many of you know, there will be a change next year in the transition dates for US daylight saving time. I won't go into all the gory details here, but if you want them follow this link http://www.microsoft.com/windows/timezone/dst2007.mspx This site will be updated to provide all the latest information about daylight saving time, including updates from Microsoft products affected by daylight saving time, as well as links to KB articles when they are available.
The Exchange team, along with Windows and Office have been giving this a lot of attention. We will be providing, free of charge, a solution for Exchange products in mainstream support. This solution will consist of changes in CDO to support these new dates as well as rebasing tool for calendar items that are already existent in users calendars. This rebasing tool is a server side tool. There will also be a client side tool available from Outlook. For products that are no longer under Mainstream support, these non-security updates will only be offered to customers that have an Extended Hotfix Agreement. For more information on the current support status of your Microsoft products and the Support Lifecycle Policy, please visit http://support.microsoft.com/lifecycle.
