I keep getting the error during install. The old exchange server was gracefully uninstalled and there are no traces of Exchange servers or databases in DC when viewing with ADSI edit, nor any exchange security group/users in AD.
I have tried running the setup.exe GUI, as well as setup.exe with all of the /Prepare switches
The Exchange is a new new build 2013 SP1 on Server 2012
Domain functional level is set to server 2012 and the Exchange administrator is a member of the domain, schema, enterprise admins. I have also tried setting each of those groups as the primary group for the administrator.
Any help is appreciated, been at this for days now.
