Hi
Exchange 2010 users are NOT able to connect to their mailboxes when they go through exchange 2013 OWA address. We get a message that says following ---> "Something went wrong"
Following is our URL. The address is pointing to 2013 CAS loadbalancer VIP. Outlook anywhere is working fine. What is going on?
Important: All my exchange 2010 / 2013 URIs are the same as suggested by Microsoft (Owa, ecp, activesync, ews, autodiscover): --> mail.domain.com/XXX
