I have just setup OWA on an exchange 5.5 sp3 box.  When I goto
www.servername.com/exchange I get this error:

You are not authorized to view this page
HTTP Error 403 - Forbidden
Internet Explorer



1. OWA and Proxy Server (Internal LAN clients cannot access OWA)

I am having a problem between OWA and Proxy server.

When an external Internet user tries to access OWA through
http://myserver.org/exchange, it works fine. However, when an internal LAN
client tries to do it through the same address http://myserver.org/exchange,
I receive the following error message:

You are not authorized to view this page

HTTP Error 403 - Forbidden

I have tried using the "Bypass proxy server for local addresses" in my
browser, however the problem remains the same.

I have SBS 4.5, with NT4 SP6a, Exchange Server 5.5 SP3, Proxy Server 2.0
SP1, and IIS 4.

In my Web Proxy configuration, I have Packet Filtering DISABLED, and Web
Publishing ENABLED, with the option to send incoming requests to the local

I have tried to put an exception and send requests for
http://myserver.org/exchange to, which is the
internal IP number of my exchange server (which is the web server, and proxy
server as well), but it doesn't work. This is described in article Q207655
in Microsoft Knowledge Base.

I have tried with IE4 and IE5.

The rest of the services are working fine. I have an Intranet, a Web Site,
and all my users have Outlook 97 or 98. The proxy server has no problem at
all except for OWA.

Your help is most appreciated.
