MDM Sync Troubleshooting

Question

Hello everyone,

I have a remote user whose laptop isn't receiving the new password policy updates I pushed from the cloud. When they look at their work settings, it shows a generic sync failure error code. What are the first three diagnostic steps or logs I should check on that local Windows 11 machine to figure out why it's failing to talk to Microsoft Intune?

Any suggestion would be appreciated!

BR, Daniel.

Hello Daniel Wright,

To diagnose a Windows 11 Intune synchronization failure, first check the Event Viewer under the Microsoft-Windows-DeviceManagement-Enterprise-Diagnostics-Provider log to identify specific error codes. Next, generate a detailed diagnostic report using the command "mdmdiagnosticstool.exe -createclientcab " in an administrative command prompt to inspect local enrollment logs and configuration state. Finally, attempt to force a manual synchronization through the Windows Settings menu under Accounts and Access work or school; the resulting logs from this attempt will help isolate whether the issue is caused by authentication errors, network blocks, or specific policy conflicts.
