I have been hosting multiple domains on my single Exchange 2003 server for quite some time now. That is working fine, even with OWA. Now I would like to enable RPC over HTTPs for all of my hosted domains. I followed Daniel’s instructions to setup RPC over HTTPs and it works great for my main domain. How do I get the other domains to work? Any help would be greatly appreciated. Trying to get this project done ASAP.
