So it sounds like there is no way to get OWA installed on a single IIS server and have it reference multiple exchange sites.

I have a Proxy server through which OWA will be accessed. I have tried using multiple IIS servers (one for each exchange site) publishing through the Proxy Server, but can only seem to get one to work. Can anyone point me to articles or information that would help me configure the others correctly? I can see all sites within the Intranet, but can only access one ofthem through the Internet.

Thanks for your help.
