ITS has enabled modern authentication on Microsoft Outlook on March 15, 2021. Outlook on Microsoft 365 is the official email application for all faculty and staff at the University. No action is required for those running Outlook 2016 and higher. Legacy clients (any version of Outlook older than 2016) must be upgraded by April 26, 2021 to continue working.
What is Modern Authentication?
Modern Authentication is a form of identity management that provides secure user authentication. It provides Microsoft 365 the ability to issue and validate authentication and refresh tokens for email clients like Outlook. Modern authentication is supported on Office versions of 2016 and higher.
Once enabled, the sign in screen and process will change. Outlook will display this mini browser to lead the user through the authentication workflow:
You will sign in with your official university email address (email@example.com) and your NetID password.
What is Basic Authentication?
Basic Authentication is the form of identity management currently being used by UConn's Microsoft 365 tenant. When authentication is required, Outlook displays this login prompt to lead the user through the authentication workflow:
Basic Authentication is insecure and leaves accounts vulnerable to brute force or password spray attacks
Enabling Modern Authentication
Below are key dates for the enabling modern authentication:
March 15th, 2021: Modern authentication will be enabled for the UConn Microsoft 365 tenant. Modern authentication is compatible with Outlook for Mac, Outlook 2016, Outlook 2016 for Mac, Outlook 2019, Outlook 2019 for Mac, and Outlook for iOS/Android. Users do not need to make any changes. Outlook 2013 is supported, but ITS recommends updating to a newer version.
April 26, 2021: ITS will disable basic authentication. This means that users will be unable to login and use Outlook 2010 and older versions of Outlook for iOS/Android. Specifically, ITS will disable basic authentication for Exchange Active Sync, Autodiscover, MAPI over HTTP, and Outlook Anywhere. Legacy protocols, such as IMAP4, POP3 and Authenticated SMTP, will continue to work.
If you have a university managed computer (ITS provides your support), you can install an updated version of Office through the Software Center. To upgrade to the most recent version of Office on a personal device or if you are supported by IT professionals specific to your area, please contact your local IT department.
For personal devices used for work, you can install Office from the Microsoft 365 portal.
