I am trying to upgrade my (small, ie 50 mailboxes) existing environment (Exchange 2010 SP3 running on Win28k, two DCs) to Exchange 2013.
So I fired up a brand new Windows Server 2012R2, installed Exchange 2013, installed CU8. (new Hostname, IP etc)
The console is working fine. But when I try to connect to the eac (https://HOSTNAME/OWA) or ECP I getting this message: (Note I try to login with my Administrator or user credentials).
:-( something went wrong Sorry, we can't get that information right now. Please try again later. If the problem continues, contact your helpdesk
Thats it. No event-log entrys etc.
Checked also the bindings of IIS. Removed the 127.0.0.1 bindings. Didnt helped me.
What is wrong? I also tried reinstalling the new Server. Same thing.
