My work has Office365 email (not sure if that's the same as exchange or not) and we recently instituted MFA. I have been using Microsoft Outlook and the Windows 10 Mail app to access this account. Both continued to work fine after the MFA was setup. But I just got a new laptop and on this machine I cannot add the Office 365 account to Windows Mail. I can access it in Outlook, but the Mail app returns "Check your information and try again. You may have just mistyped your password".
To test this more, I tried setting up new accounts in the Windows Mail app on other computers and I get the same error. The funny thing is that I know the mail app works because all of my older installations of it (from before MFA was setup) can access the account. I am assuming that the MFA is what is causing the issue, but I don't know for sure.
Has anyone run into this? Is there a different way to configure an account in Windows Mail, or is there a way to copy my account information from one computer, where it works, to another where it doesn't?
