I'm preparing to install Exchange 2007 for the second time on my Windows 2003 environment. A while back I had configured Exchange 2003 but ended up removing this server from my environment without uninstalling Exchange 2003 or removing the server from AD. In order to start fresh, I want to delete any instances of Exchange 2003 and Exchange 2007 from my environment. I noticed when using the ADSI Edit utility, I see many entries with
CN=ms-Exch under the Schema Tab. I have already delete Exchange instances from the Domain Tab. Can I delete all of the entries that have CN=ms-Exch next to them? Are they all part of either an old installation of Exchange 2003 or Exchange 2007? Please advise. Thank you.
