How do I access Microsoft Office on my personally owned mobile device? Go to your app store on your mobile device (iTunes for iOS devices, Google Play Store for Android) Search for the Office 365 app you need to install. (Note: On iPad, you may need to change search setting to 'iPhone apps only'. The iPhone app can be used on iPads, but is not compatible on 1st and 2nd generation iPads.) Install the app on your device. After the installation is complete, open the app. When prompted, enter your full EWU email address. Select Organization account and type your EWU email password.
