Which Office 365 applications require Duo?

  • Microsoft Office 2016, Office 365, and Office 2019 on PCs and Macs
  • Outlook Mobile app for iOS and Android <-- RECOMMENDED
    • If you have an older Android phone, you may need to use the Outlook Mobile app or upgrade your phone as the 'native' mail app does not support 'modern authentication', a requirement to use Duo with the Office 365 service. You can download the app from the app store.
  • Apple and iOS Mail app
    • Some iOS users may need to remove and re-add their Office 365 accounts to get Duo to work. Instructions on how to do this can be found here. Alternatively, we recommend that you download the Outlook Mobile app instead of the Apple and iOS Mail app.
  • UCI Outlook Web Access (OWA) at https://outlook.com/uci.edu

OIT will email you when your department will be required to start using Duo with Office 365.

 

Do I have to use Duo every time I check my email?

No. The vast majority of our users check their email using the Outlook desktop client or Apple Mail which doesn't require you to enter your password when you open them; therefore, you don't need to use Duo everyday.

You will have to use Duo each day if you check your email via Outlook on the Web (aka OWA) at https://outlook.com/uci.edu.

Similarly, you'll only have to use Duo with Office 365 if:

  • You get a new computer or device and need to add your account.
  • You change your password. Each device will require you to re-enter your new password, so you'll have to use Duo as your '2nd factor'.
