After enforcing 2FA in Office 365 and if you are trying to configure Outlook 2016 for email, and Outlook keeps rejecting the password that you have been using and that works with OWA, while if you try the App Password it works in Outlook, then you might want to add a registry key to enable and enforce Modern Authentication. Outlook 2010 doesn’t support Modern Authentication Outlook 2013 supports Modern Authentication but you need to add the following two registry keys. DWORD and set to i HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\EnableADAL HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\Version The following key will enforce it. HKEY_CURRENT_USER\Software\Microsoft\Exchange\AlwaysUseMSOAuthForAutoDiscover Outlook 2016 supports modern authentication and it is ON by default but we’ve had to enforce it in some instances because Outlook kept prompting for a password and wouldn’t take the password that worked with OWA but Outlook worked with App Password. Enforcing Modern Authentication made Outlook 2016 accept the regular office 365 password (that worked OWA password). Add the following DWORD and set to 1 HKEY_CURRENT_USER\Software\Microsoft\Exchange\AlwaysUseMSOAuthForAutoDiscover Note: registry changes might result in problems and serious issues with computers and software. Do it at your own risk. Share this entry 0 REPLIES Leave a Reply Want to join the discussion? Feel free to contribute!
