User in remote country can open and connect/chat with OCS - the server is here in USA. They are on a MPLS link back to us here. Please read all of this before you comment right away from your google search....
(1) : In the upper right corner of the OCS Screen, we get "Outlook Integration Error" - when clicking on it I get this error - Communicator could not determine the location of your exchange web services
(2) - Out of office assistant give me the error - "Your out of office settings cannot be displayed, because the server is currently unavailable. Try again later.
(3) Users at this site cannot pull up Outlook Web Access. They are in Japan, but they can pull up from home just fine.
This is the 32 bit version of Outlook and OCS. tracert looks OK, pings work great to the CAS Hub. I can even ping the URL for OWA. Please help me.
