I have a mixed environment of exchange 2003 and exchange 2007 servers. How can I make sure that this upcoming weekend the time change will go over smoothly? I want to make sure that calendar appointments are updated correctly and not an hour ahead. Currently on the exchange 2003 running service pack 2. and exchange 2007 SP2.

You shouldn't have any problems as the majority of the kinks were worked out in regards to DST when the Government changed everything in 2007. But to be on the same side, make sure you are up to date on your windows and Exchange patches, they go a long way. Also you can check the following site to make sure you got everything: http://support.microsoft.com/gp/cp_dstDJ Grijalva | MCITP: EMA 2007/2010 | www.persistentcerebro.com
