This article was previously published under Q293098



SYMPTOMS
You may receive the following error when you are trying to access the Outlook Web Access (OWA) logon page from a location that is external to your Proxy server:

HTTP 404 Page Cannot Be Found

You are also unable to log on to OWA from inside your network to bypass the Proxy server.



CAUSE
This behavior occurs because OWA and Proxy Server are running on separate computers, and you did not configure Web Publishing to send requests to another Web server in Proxy Server.



RESOLUTION
To resolve this behavior, enable Web Publishing to send requests to another Web server:
 * 1) Start Internet Service Manager (ISM), which starts the Microsoft Management Console (MMC) Internet Information Server (IIS) snap-in.
 * 2) On the Action menu, click Web Proxy, and then click Properties.
 * 3) On the Publishing tab, click to select the Enable Web Publishing check box.
 * 4) Click Sent to another web server.
 * 5) Type the internal IP address or the NetBIOS name of the OWA server. You can also use the fully qualified domain name as long as the name can be resolved.

Note: If more than one Web server exists, refer to the articles that are listed in the &quot;More Information&quot; section in this article.
