I have an Exchange 2003 SP2 FE/BE topology where the company is hosting two separate SMTP domains for two different sub-companies, so I created an additional OWA website as per this article.
Everything works fine: users in the first company access OWA via http://webservice.company1.com and users in the second one go through http://webservice.company2.com.
Now the customer is requesting RPC/HTTPS access for users in the second company, but using the address http://webservice.company2.com. It doesn't work, because the additional Exchange HTTP Virtual Server in the front-end server doesn't have the required /Rpc virtual directory; howewer, I'm unable to add it: the whole website seems to be managed by Exchange, and if I manually create virtual directories in it via the IIS manager they just don't work (404 error).
Is there any way to implement RPC/HTTPS in an additional web site which is running an Exchange HTTP Virtual Server?
