Frequently Asked Questions about Modern Email Authentication

Will I be prompted for two-step authentication every time I use my email?
You will be prompted every time you log in to your email and the first time you configure your email client or app.
How long will this change limit my email access on my laptop, desktop computer, VDI, or mobile device?
The change should take up to one hour. If your email stops working and does not start re-downloading within an hour, you should delete your mail profile from your device and reconfigure it. Configuration instructions for Windows or Mac desktop clients, iOS devices, Android devices, and Linux are available on the Office 365 Configuration Instructions webpage. This varies by device. In many cases access will be limited for a few minutes or hours; in rare cases it may be limited for several days.
How might my mobile device, laptop, or desktop be affected by this change?

How the change affects you depends on how your devices are configured. To implement the change on email applications installed on your computing devices (e.g, Outlook, Apple Mail, Thunderbird), your email configuration may need to be updated. If your email client is already configured for modern authentication, you will not notice any change when your account is updated. If you have difficulty accessing your email after the change, you will need to manually reconfigure your email. Configuration instructions are available on the Office 365 Configuration Instructions webpage. If reconfiguration does not resolve the problem, please submit a Help request.

Here’s what to expect if you access your email on your mobile device, laptop, or desktop:

  • iOS: If your iOS device is enrolled in Stanford's Mobile Device Management (MDM) (also called AirWatch) and meets the minimum system requirements, this change should happen automatically within an hour of the time that is specified in your notification. If your iOS device is not enrolled in MDM, and you have an issue with your email after the time the change is scheduled, you may need to reconfigure your email manually.
  • Android: Whether or not your Android device is enrolled in MDM, if you have an issue with your email after the time that is specified in your notification, you may need to reconfigure your email manually.  
  • Laptops, desktops, and VDIs:
    • If you use Windows, in most cases this change should happen automatically within an hour of the time that is specified in your notification.
    • If you use macOS and you purchased your device within the last two years, in most cases this change should happen automatically within an hour of the time that is specified in the notification.
    • If you use Linux and you have difficulty accessing your email after the transition time that is specified in your notification, you may need to reconfigure your email manually.

What Office 365 features will be affected by this change?
