Is it possible to setup Autodiscover for your domain.com without the use of an Exchange Server in the back-end? I already have an IMAP/POP3/SMTP hMailServer running on Windows with IIS Web Server. When I bind the domain to use the autodiscover.domain.com/Autodiscover/Autodiscover.xml, I can view the XML output in a browser.
However, when I try to setup the mail client, Outlook 2013, it does not want to take it. It asks me to allow the certificate because the domain name is different, so I allow it. Then it just tries continuesly... After a while I'm stuck with a 'Server could not establish a secure connection, would you like to try uncrypted?'
I have followed quite a number of online documentation but 99% of them reference back to Exchange - which works. My scenario is Exchange-less.
