I am installing the Mailbox and Client Access Roles into a Server 2012 server, and this server already has IIS installed on it and hosting a Web Application in the Default Web Site. That already existing website has had it's http port bound to 85 instead of 80 though (which I would have thought made this easier).
I cannot find a way that I can specify which Website for it to install the Client Access. Letting it install by itself merges with the existing web application, and the SSL settings cause it to break.
Any insight would be helpful.
