Hello,
We are working on our migration to Exchange 2013. When we try to login to OWA 2013 using a mailbox that is still located on out 2010 mailbox server we receive an OWA 2013 error page that says "Something went wrong" with no other information.
1. Should OWA 2013 be able to proxy the connections to the 2010 mailbox?
2. Any ideas where to start troubleshooting this?
Thank you,
Matt
