Hi,
I installed Exchange 2013 RTM in existing environment with Exchange 2010 Sp3 in our test environment. After installing Exchange 2013 RTM I checked when I access OWA using Internal URl it redirected to Exchange 2010 CAS server's Internal URL and I was
able to access Exchange 2010 mailbox.
I upgraded to CU2 and now Exchange 2013 internal URl not re-directing it to Exchange 2010 mailbox anymore. I checked all the settings on virtual directories and made sure that FBA authentication is selected. It is a test environment and I just wanted
to test the re-direction in co-existence environment using Internal URL. It should work out of the box but not sure what happened. There was no issue in CU2 instllation.
Exchange 2013 CAS and mailbox roles are on separate servers. Same with Exchange 2010. There is no certificate 3rd party certificate install on CAS servers since it is a test environment.
Not sure what else can I check.
I appreciate if any help I can get.
Thanks,
Regards
Raman
