If you’re having problems deploying, managing, and apply Microsoft Intune policies for Windows 10, this guide can provide some information and the process to troubleshoot and diagnose policy.
Microsoft Intune has many error codes for every action, from enrollment to actions such as Software Update.
When you applied policies from Microsoft Intune is start to apply few actions such as Remediation to the Windows 10 devices.
Once the policy is failed, you may receive a Remediation error with a known code. The Remediation failed error message is returned by the client when we issue the SET command on the OMA-URI’s required to configure the target setting.

How to Troubleshoot Intune Remediation Error

First thing first, start with Event Viewer and to the following Event Log.

Application and Services Logs > Microsoft > Windows > DeviceManagement-Enterprise-Diagnostics-Provider. You’ll see two logs, Admin and Operational

Next, go to the Admin log and check if you’ve some errors, and you should see some high-level error messages which might point to the issue.

If these error messages in the Admin log are still unhelpful, you’ve another option, and that’s to enable Debug logging on the DeviceManagement-Enterprise-Diagnostics-Provider.
To do this, from the View menu in Event Viewer, enable the Show Analytic and Debug Logs option. This will likely make your event viewer window flash like crazy for a minute or two, but it’s enabling extra logs, and the UI doesn’t like it much.

Once enabled, you’ll now see a Debug log option in the DeviceManagement-Enterprise-Diagnostics-Provider. Now enable the log by right-clicking on the log and selecting Enable Log.

Once you enabled the Debug Log to rerun the action and sync your Sync action settings (from the Account settings).
