we use Outlook web access on our exchange server on port 8080. We have a IIS web server that is taking up port 80.. What the problem is that some conference centers in the world are blocking port 8080 and only letting port 80 in and out.. I want to setup a virtual directory on the IIS server (exchange) to point to the OWA server. How do I do that ? Do I have to share the folder on the Exchange server were the OWA is sitting ?
