Summary
In this module, you explored how to diagnose and resolve device and policy issues in Microsoft Intune using a systematic approach. You learned a five-phase troubleshooting workflow that moves from information gathering and service health checks through portal-based diagnostics, policy status investigation, and client-side log analysis. You applied this workflow to common enrollment and compliance failures, identified and resolved configuration profile conflicts, and explored how to gather diagnostic logs remotely and locally across Windows and mobile platforms.
You also learned how Remediations automate the detection and correction of recurring device issues using PowerShell scripts, turning reactive troubleshooting into proactive maintenance. By combining Detection scripts that identify problems with Remediation scripts that fix them automatically, you can resolve common issues before users notice them.
The key to effective troubleshooting is starting with the right diagnostic layer. Always verify Intune service health before investigating individual devices, use the Troubleshooting portal to quickly validate licensing and group membership, and remember that policy conflicts require exclusion groups rather than policy changes. When you encounter enrollment failures, check licensing, device platform restrictions, and device limits first. For compliance issues, always verify the device has synced recently before investigating the failing setting.
As you continue managing endpoints with Intune, you can return to the five-phase workflow whenever you encounter an unfamiliar issue. This structured approach ensures you investigate systematically rather than guessing, saving time and preventing unnecessary policy changes that can create new problems.
