Issue Encountered During Windows 365 Defender Onboarding - AADSTS50131 Error

Question

While in the process of onboarding Windows 365 Defender and connecting it to Sentinel, we have encountered an issue that is currently preventing us from completing the installation successfully.

The exact nature of the issue is not clear to us, and we require assistance in resolving it promptly.

We have attempted a workaround from the following link (https://www.graber.cloud/en/aadsts50131-device-not-required-state/#:~:text=the%20AADSTS50131%20error-,The%20error%20%22AADSTS50131%3A%20Device%20is%20not%20in%20required%20device%20state,developments%20that%20address%20the%20APIs), but unfortunately, it did not resolve the problem.

Could you please provide guidance or steps on how to diagnose and rectify this problem?

Answer 1

Hello @Riadh Zehani , the AADSTS50131 error while connecting Microsoft 365 Defender to Sentinel is caused by classic conditional access policies created by the Intune integration. Re-attempt the connection this time from an Azure AD registered device.
