Hey folks, To tell the true I'm still interesting in Exchange 2007 compatibility with Windows Server 2008 R2 issue. Can someone explain me. My question is not related to DC on WS2008 R2. I just tried to install MailBox rule on WS 2008 R2 and there were problem on my way to install it(something related to access denied). As far as I found out I have to change in setup compatibility options. Actually when I have changed it started to work normally. That's what I wanted to know why? Does it affect to server post-installation works? Thanks beforehand.

Hi,It is not supported yet to run Exchange 2007 on Windows server 2008 R2.http://msexchangeteam.com/archive/2009/11/30/453327.aspxLeif
