I have installed Exchange 2007 into an existing Excahnge 2003 organization.  We now find out that we have to support services that rely on Exch2k3.  Does anyone know if it is possible to install an Exc2k3 into an org. after installing Exch2k7.

i tried of playing around like your scenario

Where i uninstalled exchange 2003 and then reinstalled it but there i faced lots of issue.

I never suggest anyone to go through this scenario where we need to install exchange 2003 in Exchange 2007 envmnt.
First is version change of 2007 is 8.0 and this can't find 6.0
Second like mailflow issue and other stuff.

DISASTER - Please help

I was running Exchange 2003 previously unless i decided to upgrade to Exchange 2007 and installed x64 version with most common 4 roles. Installation went with a few hickups but at the end i had both in co-existance. Installed all the patches required etc. Since POP3 is not availble in GUI in 2k7 so i opted to go for SP1 on Exchange 2k7 also (My badluck i guess). I installed SP2 for windows server 2003 x64 smoothly. SP1 installation stoped in the middle and 2k7 Inf. Store dismounted. Now i didnt have the option of moving all mailboxes from 2k3 to 2k7. I tried to uninstall 2k7 but it even got worse. Removed Uni Comm and then client access but uninstalltion didnt allow further promting for message  that Exchange installation doesnt exist. I tried all options to remove but no use. in the mean time Existing Exchange 2003 server went down due to some reason. I decided to live with old version 2003 and shift it to new hardware that of 2007. So i shutdown 2k3 server and installed New OS on other machine with new server name. Started a fresh installation of Exchange 2003 in hope that i would import all exmerge backup in newly created server. But alfter installation inf. store on new 2k3 server doesnt load giving errors. Now i have old and new 2k3 at hand and previous installation of 2007 leftovers in Active directory.

Please advise me what to do now?
