My experience with Proxy is that your browser my be set to 8080 but 443
by default is SSL port for the browser and OWA. I had users who could
not get to normal SSL sites and I had to open 443 out and 443 in for my
SSL to my servers. If you change the default SSL port then your browsers
will try to hit 443 unless they put :8080 (or whatever port you are
using for SSL) in the URL.

This was the issues in my environment, it could be different in yours.

Wouldn't that go through port 1080/8080 (ie. The proxy port)?

Most likely the client network does not have SSL (port 443) open for
access. That would be my guess.

Hi all,

I have an Exch 5.5 + OWA in a DMZ.  My users have been reporting that
they cannot get through OWA when they're on someone else's LAN.

Further investigation showed that these users were connecting through a
proxy.

The problem is that after they enter their alias and click the
hyperlink, the authentication box does not pop up, but instead the
client's browser goes blank.

The the proxy (the one the client is connecting through) reports an
'Authentication Failed' error.


What's going on?  Any idea how we can solve this?

Thanks and regards
