I have an Exchange 2010 cas server that works fine with OWA internally and over the internet, and Outlook Anywhere works fine internally. When I try to access it outside the office though, the authentication prompt just keeps coming up for any user I try
it on. I have used the connectivity analyzer, and it gives me what I've pasted below. I have disabled OA and uninstalled the RPC, rebooted and installed again and set it back up, with no luck. I've also tried both NTLM and Basic setups on the server side,
and they both give the same error from outside the office. I also have checked my firewall settings, and everything is good. The only thing I can think of is that my reverse proxy is causing an issue. We have RHEL 5 with apache doing reverse proxy. Everything
else works though, so I'm not sure why OA wouldn't?
