Additional Tips

  • You can return to this Account screen and click Sign Out underneath your account name to sign out of the Microsoft app. Sometimes signing out of an app and then signing back in can resolve issues with an app.
  • You can click Switch Account underneath your account name to sign in with a different Microsoft account, such as a personal account. However, make sure you select your CSUF Microsoft account to enable any licenses (such as the Office 365 license) or to save your work to your CSUF OneDrive account.
