Entra Failing to enable MFA - Service Health says healthy

Question

I'm trying to enable users in Entra for MFA. This is a common worklfow for us. I'm receiving repeated errors that state "Failed to enable multi-factor authentication - unexpected error when enabling multi-factor authenitcation". Help documentation is no help. Any advice appreciated. Thank you.

Answer 1

To resolve the "Failed to enable multi-factor authentication - unexpected error" in Entra, try these steps:

1. Check User Licenses: Ensure users have the correct licenses (e.g., Azure AD Premium P1) for MFA.
2. Verify MFA Settings: Go to Azure AD > Security > Multi-Factor Authentication and confirm MFA is enabled.
3. Review Conditional Access Policies: Ensure no conflicting policies are blocking MFA.
4. Reset MFA Registration: Reset MFA for users to clear any corrupt data.
5. Check Service Health: Review Microsoft 365 service status for any ongoing issues.
6. Test with Another User: Try enabling MFA for a different user to rule out individual issues.
7. Use PowerShell: Enable MFA via PowerShell if the portal fails.
8. Contact Support: Reach out to Microsoft support if the issue persists.
