Apple iOS
On iOS, Exchange ActiveSync is supported. It has the advantage of supporting push email (i.e. you are immediately notified of incoming messages), but has some limitations, e.g. it does not support more than three email addresses per contact in your address book. Follow the steps below if you decide to use Exchange instead.
Open the Settings app, tap Mail, tap Accounts, tap Add Account, select Exchange.
Enter your email address (user_email@your_domain.com) and tap Next.
Enter your password, tap Next again.
Finally, tap Save.
