I have a connection issue when using Outlook 2016 to connect to my Exchange 2010 server externally using Outlook anywhere.
Historically with any previous version of Outlook I needed to tell it to use HTTP on slow/fast the proxy tab via Outlook. As long as did this, external clients would connect immediately and everything worked fine. If didn't do this, Outlook would always try tcp first, which would produce a very long connection delay since RPC/TCP won't work externally. After it timed out, it would then connect via HTTP and everything would work fine after that.
In Outlook 2016, that proxy tab is gone, so as a result I get a big 30 second delay before Outlook switches to HTTP and everything works fine.
I can see through the Outlook Connectivity monitor that it is trying TCP first, causing the delay. Without the proxy tab, how can I tell Outlook 2016 to just use HTTP and be done with it?
