Exchange 2010 Install Fails It appears there is a ghost exchange 2003 server
Posted on 2011-03-08
I am trying to install Exchange 2010 to evaluate. I should say I have never used exchange before so go easy on me.
I have cloned (VMware) our domain controller and placed it into an isolated network so I can do the practice set up against a copy of our production environment. but when I try to install exchange I get errors.
1) The Exchange organization is not in native mode
2) One or more servers in the existing organization is running exchange server 2003 without sp2.
We do not have an exchange server and so far as I know never have. I am assuming my predecessor must have installed exchange 2003 at some point to evaluate, but did it against the production environment. How do I clean up whatever is still floating around so I can install exchange? I have done some googling and have read that on the older versions there was an update.exe /RemoveOrg that would clean up the leftovers but I can't seem to find a similar function for exchange 2010
