Well the Exchange Fix is out: Update for daylight saving time changes in 2007 for Exchange 2003. This fix updates a number of files including Cdo.dll, Cdoex.dll, Davex.dll, Excdo.dll and Exoledb.dll
As you probably know, Blackberry Enterprise Server (BES) uses CDO for a lot of it’s work. Typically the version of CDO you are using with Exchange should match on your BES server, so with this DST issue what is the deal?
Well RIM have a few pages that might be interested to look at. Hope this helps.
BlackBerry Enterprise Server for Microsoft Exchange: http://www.blackberry.com/select/dst2007/planned_resolutions/enterpriseserver/exchange/index.shtml
Apply the appropriate configuration updates and patches before the first 2007 DST transition on 11 March 2007. You do not have to simultaneously apply the updates and patches to BlackBerry devices and the Microsoft Exchange Server, but all patches should be rolled out before the transition date. You can apply the updates as soon as they are available.
RIM plans to deliver the patches and updates by early February.
The Microsoft Exchange 2007 DST update version is 6.5.7830.0 (a higher version than the 2007 time zone beta). It contains the fixes for the United States and Canadian time zones, but it does not currently contain fixes for Mexico. This information will be confirmed when Microsoft releases the new version of the DST update in late January 2007.
Impact to the Microsoft Exchange Environment
No patches to the BlackBerry Enterprise Server for Microsoft Exchange are required from Research In Motion.
BlackBerry Enterprise Server for Microsoft Exchange administrators must install the latest Microsoft CDO DST update. Visit support.microsoft.com/?kbid=926666 for more information and to download a trial version of this update.
Version 6.5 of CDO, which is included with the DST update, is intended for use with Microsoft Exchange 2003 System Manager. RIM recommends that administrators upgrade the BlackBerry Enterprise Server computer to use the Microsoft Exchange 2003 System Manager. RIM is currently testing the impact of running this Microsoft CDO update on other messaging and collaboration servers.
