Viewing 1 post (of 1 total) Author Posts AnonymousGuest May 12, 2011 at 4:02 pm #154599 One of our clients recently requested their own Exchange server, and we deployed a single Exchange 2010 SP1 server for them. For inexplicable reasons, the client now wants to downgrade from Exchange 2010 to Exchange 2007. :-x Is this possible? From what I understand there are significant differences in the schema. Can we deploy the Exch2007 server in co-existance with 2010, then simply uninstall the 2010 server? Any help appreciated.
