At the moment I am having an issue where one users active at one site cannot see the calendar availability of users at the second site. CAS01 is at our primary site, and CAS02 is at our secondary. Users active at the same site can see each other's calendars in outlook 2010, but it does not work cross-site.
Is this an issue with availability URLs? I have checked these and cannot find anything wrong. What about firewall rules? Do i need specific rules on our firewalls to allow the traffic?
