Scenario:
Exchange 2010 Mailbox Server
Exchange 2010 CAS Server
Exchange 2013 MB/CAS Server
In the processes of migrating users to 2013 in a long term effort to remove 2010 from the domain. All servers are local, no cloud based Exchange. All access is internal, no external.
PROBLEM:
Installed CU6 on the 2013 MB/CAS server which, upon completion, has disabled the ability for the ECP page on 2013 to display. Can access the URL /owa/auth.owa">https://<FQDN2013.whatever.com>/owa/auth.owa
The 2010 ECP works fine...no problems there.
I have searched nearly every possible sting combo on Google and tried about every option that I have come across out there...from rebuilding the VD's, to resetting the authorizations...and am now at a loss. Again, before the CU6 update, ECP worked both on 2010 and 2013, but something in the CU has smashed the ability for ECP to work on 2013.
So...I turn to this forum.
Appreciate the assistance.
