I have a new server and was going to install Windows 2008 Server Enterprise on it. However, we don't have Exchange 2007 but we do have Exchange 2003 Enterprise. Can you install Exchange 2003 or Windows 2008? I can't seem to find this information anywhere.Thanks,Darla Denton

You cannot install Exchange 2003 on Windows 2008 Server. Not supported.MVP Exchange Server

Darla, No you cannot. It can only be installed on 2000, 2003 or 2003 R2. http://technet.microsoft.com/en-us/library/cc164322(EXCHG.65).aspxMark Morowczynski|MCT| MCSE 2003:Messaging, Security|MCITP:ES, SA,EA|MCTS:Windows Mobile Admin|Security+|http://almostdailytech.com

Yes what John said, it is not supported. Below information says clearly... :)-==-==-==-==-==-==-==-==-==-While you cannot install Exchange 2007 RTM on Windows Server 2008, Exchange 2007 RTM will be supported with Windows Server 2008 RTM domain controllers. Exchange 2003 Service Pack 2 will be similarly supported: Exchange 2003 cannot be installed on Windows Server 2008, but will be supported with Windows Server 2008 domain controllers. - http://msexchangeteam.com/archive/2007/08/16/446709.aspx-==-==-==-==-==-==-==-==-==-Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com
