Our UConn community may experience issues with their Outlook email client and Microsoft 365 applications when two-factor authentication (2FA) is activated for the first time. Generally, the process for correcting the issue involves signing out or removing the email profile and re-adding it to the device.

Some apps, such as Apple Mail, use the term “Delete” when referring to removing an email account from your device. This refers to deleting the connection to your UConn email on your device. Rest assured, your UConn email account and all contents will remain safe in UConn’s Office 365 servers, and will sync back down to your device once you sign back in.
Microsoft 365 Applications
On November 10, 2022, 2FA will be required to log in to Microsoft 365 applications (Outlook, Teams, OneDrive, Word, Excel, etc.). In most cases, you just need to sign in when prompted and respond to the Duo prompt.
After you respond to a Duo prompt, you may see a second screen from Duo if you were accessing the application online via a browser. The screen will ask if you want to “trust the browser.” Click Yes to reduce the frequency of authentication prompts from Duo.
You may also see a popup from Microsoft asking if you want “Stay Signed in?” Click yes to reduce the frequency of sign-in prompts.
You may also see another message from Microsoft about staying signed in. This message incorporates boilerplate language from Microsoft that is not customized for UConn. If you click OK, you will automatically be signed into other Microsoft 365 apps. For example, if you sign into Outlook and get this prompt, selecting OK will result in them being automatically signed into OneDrive, Teams, Word, etc. when attempting opening those applications.
Troubleshooting Sign In Issues with Microsoft 365
The best way to remedy any complications with Microsoft 365 applications after enabling 2FA is to:
Sign out of the application or QUIT/CLOSE the application if you cannot sign out.
Sign back into the application which should prompt 2FA authentication via Duo.
If the user is not prompted for Duo authentication, assistance from the TSC may be necessary to clear their profile from the device in some fashion.
- Opt to “Trust this Device” to not be prompted by Duo for another 30 days on that device.
