Hi You can install all the available updates if you wish but none of these are required for Exchange 2010 coexistence - only Exchange 2007 SP2 is required. Cheers, Steve

Hi You had better install all ru on your exchange server. Exchange 2007 ru4 and ru6 fix attachment problem. I believe it is important. http://support.microsoft.com/kb/2543879 TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.comTerence Yu TechNet Community Support

HI there, If you are migration soon I would not worry about it. I would make sure Exchange 2010 and it's Sp and RU level is current before the migration. Good luck with migration ocd Oz Casey, Dedeal MCITP (EMA), MCITP (EA), MCITP (SA) Visit smtp25.blogspot.com Visit Telnet25.wordpress.com This posting is provided AS-IS with no warranties or guarantees and confers no rights.

Thanks All,.. Thanks for the update,.. :)

Hi Team, Im planing to install Exchange 2007 SP3. my current Exchange version is Exchange 2007 SP1 with RU6. this because we are plaing to deploy Exchange 2010 SP1 in our environment. so my question is,.. Do i want to install RU for SP3 or shall i keep the system with SP3 only? (withing 1 week we will be migrate to Exchange 2010)
