Hi all, I have deployed Exchange 2007 and i joined it to a domain which is part of a big lab.For couple of reasons i had to remove the 64-bit server (it was borrowed). Now I'm planning to build another Exchange 2003 and join it to the same domain to replace the Exch2007. 1st of all, is it doable and supported/ if it's supported, is there any consideration i have to take into consideration? I appreciate your feedback Fady

It is not supported to add an exchange 2003 server to a native 2007 enviroment. I dont think it's spelled out to include the later removal of the only e2k7 server, but i would imagine the same holds true - as e2k7 makes permenant changes to the schema and AD. but thats not a definite answer. i'll post back if i find more.
