Hello,
I have a Lab Server running Exchange 2013 SP1 CU5 on Windows Server 2012 R2. ECP/OWA work fine. But when I click on certain buttons on the Exchange configuration web page, the pages will not open. For example: I cannot Edit the email address in Public Folders and I cannot add a Smart Host in Send Connectors. Please note I did not have this problem on a fresh Install of both O/S and Exchange Server 2013 SP1 CU4. But after I did a fresh Install again of the O/S and Exchange 2013 SP1 CU4 I had the same problem of Exchange configuration web pages not opening on Exchange 2013 SP1 CU4. So the problem I faced was on both CU4 and CU5.
Some help would be useful.
Thank you.
