[Exchange] I entered my Email and Password correctly, why is your app asking for Server and Domain now?

If you are seeing a screen like this, it means your Mail-Server is not auto-discoverable over the Internet based on the email and password you entered.

You need to enter your mail server settings including the server host and your username (may be different from your email). Some organizations require a Windows domain field as well and if so please enter your Windows domain name on the screen too.

You may have been given email setup instructions on how to setup email on iOS by your Mail Administrator. Please consult such instructions. If you do not have this information please contact your Mail Administrator for it.

A typo in your email or password would also cause auto-discover process failure. If you want to retry auto-discover, you can go back to the simple login screen (tap 'Hide advanced settings').
