Instructions on installing Microsoft 365 Apps for enterprise on mobile devices are available on the official Microsoft Support website. Once you install the apps, you will need to sign in to your netid@gmu.edu account and authenticate using Duo Two-Factor Authentication (2FA).

Note: Not all mobile device operating systems support 2FA. For more information, visit Microsoft Support’s article How modern authentication works for Office 2013, Office 2016, and Office 2019 client apps.
