2 Exchange 2013 servers same forest. Outlook 2010 and 2013. Users on the same server can see each others free/busy. If a user on server 1 looks up free/busy info for any user or resource mailbox that is on server 2 they cannot see free/busy and vice versa.

Test Email Autoconfig does not show any errors. Outlook Anywhere *seems* to be working just fine. There are still EX2010 servers in the environment, too, but there are no mailboxes on them anymore as we're migrating to 2013.

help?
