Adding an Exchange Email account to the iPhone default mail app

1. Open the settings app on your phone and find mail
2. Click Mail accounts, then add account
3. Select "Microsoft Exchange"
4. Enter the Email address here, and add something to the description box (I use "Work Email" for the description for example)
5. Click "Sign in" (Make sure not to click configure manually)
6. You may get a pop up saying something along the lines of "Settings wants to Use microsoftonline.com to sign in", make sure to press continue here
7. It will load the microsoft login page, sign in with your email and password here
8. You can then select what you want to sync (mail, contacts, calendars etc) and click Save
