Redirecting OWA Users to the Correct Directories and Protocols with ISA Server 2006
Thomas Shinder wrote a two part article series about how to redirect OWA users to the correct directories and protocols. That article series was originally written with ISA Server 2004 in mind and can be found at:
- http://www.isaserver.org/tutorials/Redirecting-OWA...1.html
- http://www.isaserver.org/tutorials/Redirecting-OWA...2.html
With ISA Server 2006 the solution to redirect the HTTP requests to SSL (HTTPS) requests is very easily implemented by properly configure the Connections properties of the Web Listener as explained in Tom’s blog Redirecting HTTP Requests to SSL Requests using the 2006 ISA Firewall. One of the solutions to redirect the users to the /Exchange folder was to include a special path mapping translating the root path “/” to the special Exchange path “/Exchange\”. However with ISA Server 2006 this is no longer possible because it generate the Event ID 21177 as mentioned in my previous blog ISA Server 2006 and KB917025 and the following ISA Alert:
One possible solution is to include the root path “/” in the OWA web publishing rule and place the following ‘default.htm’ file in the root directory of the OWA site:
Note: you can download the above OWA_default.htm sample page at http://users.skynet.be/spouseele/OWA_Default_htm.txt. Of course don’t forget to change the URL to what is appropriate in your specific environment.

Hi Stefaan,
Pay attention to this article series, especially next week:
http://www.isaserver.org/tutorials/ISA-Firewall-Pu...1.html
I’ll be going into the details of how to create a variety of redirects using ISA 2006 to support both OWA and RPC/HTTP using a single IP addresses on the ISA Firewall’s external interface.
Thanks!
Tom

Hi Tom,
yeh, I saw your article but I was just impatient and very glad I found the route cause of my ISA 2004 to ISA 2006 migration trouble.
I’m very confident you’ll give us some very nice solutions to this ‘customer problem’.
Thanks,
Stefaan

[…] In my blog Redirecting OWA Users to the Correct Directories and Protocols with ISA Server 2006 I reported a problem with my OWA publishing rule with ISA Server 2006. Removing the special path mapping I used with ISA Server 2004 to translate the root path “/” to the special Exchange path “/Exchange” solved the problem. To resolve the redirection problem, I implemented the redirection in the ‘default.htm’ file in the root directory of the OWA site as described in my blog. […]
