Hello
i am trying to install exchange 2013 in a small test domain. My exchange 2010 is not healthy anymore. The pre-requisits check denys the installation of exchange 2013 because there was an exchange 2010 without sp3 in the domain.
The old exchange with all exchange security groups have benn deleted in the active directory. What else do I have to do for a new installation ofd exchange 2013?
Thanks for any suggestions.
Sam
