Exchange Mail does not get connected on iPhone Mail
I have an iPhone 6s+ and I'm trying to plug my exchange mail on it for a while and it keeps on telling me can't find server. The problem here is that I'm able to setup my exchange mail on Mac Mail just fine. With auto discovery and all working fine. I've also tried using the actual mail url for web version of the exchange as the server but with no avail.
iPhone 6s Plus, iOS 9.1
