On Exchange server, configuring virtual directory might be pain sometime. A simple misconfiguration of Virtual directory might be the worst nightmare, because I have been there few days back. While configuring additional CAS server after few changes done on the Virtual directory, my OWA/ECP page start to go on loop whenever I tried to get login. I was on dark what mistake I had made. So, I tried to list down what might the issue that is causing on looping of my OWA/ECP page. While listing down, I have found two things.
- SSL Certificate.
- Issue with configuration of Virtual Directory.
