Outlook Web Access did work; doesn't work with proxy now

Posted on 2002-06-03
Last Modified: 2010-03-05
We run Small Business Server 4.5 with Exchange 5.5. When we had our own internet line, Outlook Web Access worked fine. We switched over to a T1 that goes through our parent company using a proxy server. Our parent company is unfamiliar with OWA and no one uses SBS but us. What do they need to do to get this to work? Is it only opening ports? Rules for our router, thier router???
On the server and my laptop, I can browse the internet without using the proxy and I can access OWA fine. (We use Microsoft Proxy on the server, not sure how I can surf without proxy, but it only works on my Win2000 machine and server). So I guess that tells me OWA is running, and the T1 settings (or the router) isn't letting users in. Any info at all would be great. I am not sure even where to start, and I not getting much help from corporate!! thank you so much!!

If you need to access OWA from outside your companys network, port 80 has to be open for http and port 443 if your are using ssl.  Does the parent company run the proxy server?  If so they will have to open the port for you.  If you need instructions on how to do this I can provide it.

thanks for the info, seems like it would work, but our parent company has decided to set us up with VPN instead. we'll see if that ever happens! thanks again.
