I've tried ALL the supposed reg fixes, removed all credentials in Cred Manager, disconnected all Accounts in Windows. Once MFA enabled Outlook 2016 behaviour is to use *Clear rather than *Bearer (Modern Auth) and constantly prompts User for password. Scenario 1Ĭlients using Outlook 2016 (version has no bearing).

I've tried a few reg entries, clearing credentials, app passwords, etc, but nothing consistently works Outlook prompts for password and doesn't use Modern Authentication to connect to Office 365. If the issue persists after you tried above, please try to create an app password for your Office 365 account that enabled MFA We have started enabling MFA for some users and have noticed that Outlook (latest build from O365) is repeatedly prompting for password on some user's computers. Restart outlook, you should type your password /app password again and select the option to remember it. Home MFA Outlook keeps asking for password
