Apple Mail after Microsoft's MFA (Two-Factor Authentication or 2FA)

As of March 2019, Syracuse University Mail (SUMail) requires Microsoft MFA (also known as two-factor authentication or 2FA). All versions of MacOS before 10.14 Mojave do not support what is referred to as "modern authentication". When trying to access older versions of Mail, you may continually asked to log in without success. You may see the following screen asking for internal and external URLs as well as a statement that Apple Mail cannot verify the account name or password:

In order to continue to use Apple's Mail app, you will need to update MacOS to the latest version, 10.14 Mojave, which is freely available in the Mac App store. You must also remove and then re-add your SUMail account in order to Apple's Mail app to recognize the MFA/2FA. Follow the instructions listed under the "Related Articles" section for more information.

Additional work arounds include installing Microsoft office using your provided Office365 subscription, and use Outlook. You could also use Outlook's web based email on your preferred browser
