We have had OWA setup for a few months and it works with no issues. In exchange we have the internal URL as https://servername.domian.com/owa and the external URL as https://mail.xdomain.com. Both have worked without issue and connecting to the mail.xdomain.com URL from internally would redirect you to the correct address.
Now have installed the TMG Client on all our TS servers and have it automatically configure the web proxy. Once we do that, we can no longer access OWA using the internal URL. We can connect with the external URL still, but we don't want our traveling users to have to use two different URLs to access OWA. If I manually remove the web proxy in the IE settings I can connect with no issues.
The TMG logs shows this when trying to connect using the internal URL:

I'm not sure what the issue is and was hoping somebody could shed some light on this. Thanks in advance for your time! |
