Are you using classic conditional access policies? Replace them with new policies and try disabling the old ones 🙂

Thanks for the reply Julian.The actual error: AADSTS50131 (Device is not in required device state)I think I have seen this error relating to classic CA policy definitions that were created when Intune is or was connected to the Defender portal...

gem0011There is no Sentinel Apps in the Conditional Access. Thus, the only way is disable MFA in the account which you used for configure the Sentinel. Then configure the Microsoft 365 Defender Data Connector. Once configuration was completed, restore the MFA settings in the account.

Hello gem0011,I was able to resolve the matter (for me) by adjusting the classic CA policy and applying an exclusion group...You check this by:• Log in to Azure Portal• Search for or click on 'Azure AD Conditional Access'• Click on Manage &gt; Classic Policies• See under 'Policy Name' if [Windows Defender ATP] Device policy) is listed• Click on the policy and create an exclusion group...
