why does outlook keep asking for password verification

Sign into your Office 365 Admin Center using your O365 account (you will need admin permissions).įrom the navigation menu select Settings > Services & add-insįrom the list select ‎Modern authentication‎ and enable the option. This was the important step, you need to ensure Modern Authentication is enabled for your Office 365 tenant. Go to your security profile and delete any previously created app passwords for Outlook.

Remove any credentials associated with Office and your O365 account (Look for anything starting with MicrosoftOffice16.) - ensure you don’t remove credentials for accounts other than the problematic account. Remove any Outlook saved credentials using the Windows Credential ManagerĬlick start and type in credential and open Credential Manager and select Windows Credentials Office MFA enabled and configured (enforced) for my account.Latest Office applications installed on Windows 10 (1903).After numerous attempts to fix the issue, including, removing all the email accounts and trying to use the Support and Recovery Assistant for Office 365, eventually I stumbled across a solution that worked for me (as always your mileage may vary!). Recently Outlook on my Windows machines stopped working correctly, it would constantly prompt for a password and wouldn’t accept my app passwords or my actual password.

When it comes to Office 365, the most common of these is Outlook, the typical work around for Outlook is to use an app password - essentially a generated password that can be used by the application to by-pass the MFA requirement.Īpp passwords are a kludge - they are usually quite short and not very secure compared to a long password. MFA works great most of the time however it is a pain when it comes to applications that need to access your account which cannot perform the MFA dance. I’ve been using Office 365 for a long time and like a good citizen have MFA enabled for my account (in fact I have MFA enabled for everything that I can). If you have Office365 MFA enabled and Outlook constantly prompts you for a password for your Office365 account, you may need to enable Modern Authentication in your Office365 tenant.
