SCCM co-management device failed to enroll

Hi @StiFenclii-5690 ,

Thank you for posting in Microsoft Q&A forum.

1,Could you please share the screenshot to narrow down the issue? Also help examine the MDM logs on the device in the following location in Event Viewer:

Applications and Services Logs > Microsoft > Windows > DeviceManagement-Enterprise-Diagnostic-Provider > Admin

2,This issue may occur when multifactor authentication (MFA) is Enforced. It prevents the Configuration Manager client agent from enrolling the device by using the logged-in user credentials. We can use one of the following methods to fix the issue:

a,Set MFA to Enabled but not Enforced.

Microsoft Entra multifactor authentication user states

Set up multifactor authentication for Microsoft 365

b,Temporarily disable MFA during enrollment.

For more information, please refer to:

Thanks for your time. Have a nice day!

Best regards,

Simon
