While you can use either Microsoft Outlook for iOS or the built-in Mail and Calendar apps to access your Northwestern Exchange account, you will have a much better experience using Outlook. However, the choice of which app to use is yours. Instructions for configuring both can be found below. Just make sure you don't use the Office 365 app for iOS because it lacks essential functionality. Make sure you are connected to the secure Northwestern network when configuring your Northwestern Exchange account on your mobile device. Don't use Guest-Northwestern or Device-Northwestern, or any other network.
