[SOLVED] Office365 MFA enabled cannot setup outlook

This has now been updated and access from your admin page on Office365

go to Portal.office.com

Decide whether you want the following on or off to fix the issue

Turn on modern authentication - type the following:
Set-OrganizationConfig -OAuth2ClientProfileEnabled $true

Turn off modern authentication - type the following:
Set-OrganizationConfig -OAuth2ClientProfileEnabled $false

Check the status (on/off) of modern authentication:
Get-OrganizationConfig | Format-Table Name,OAuth* -Auto
If you still have the problem add the following Registry keys on the client machine to suppress WAM and revert Outlook back to ADAL:



After this, all should work as normal.
