Consider the following scenario:
HTTP Status Code: 1359 An internal error occurred
This problem occurs because of a change in Update Rollup 3 for Exchange 2007. After you install this update rollup, any request that is sent to the /owa virtual directory without a trailing slash mark (/) receives an HTTP 301 response. The HTTP 301 response redirects the client to the /owa/ virtual directory. However, ISA Server 2006 incorrectly handles the HTTP 301 response when NTLM delegation is used.
To resolve this problem, apply the hotfix that is mentioned in the following Microsoft Knowledge Base article:
(http://support.microsoft.com/kb/960148/ )Description of the ISA Server 2006 hotfix package: November 19, 2008
To work around this problem, use one of the following methods.
Method 1Configure the publishing rule to use Basic Authentication delegation.
Method 2Do not use a Web farm. Instead, publish the OWA server as a single Web server.
