Microsoft Intune troubleshooting: check-ins, policy status, enrollment errors and device actions
For Intune administrators and endpoint technicians who handle 'it didn't apply', 'it won't enroll' and 'the app never installed' tickets. Learn how and when devices check in, what each policy status means, where Windows keeps MDM and Intune Management Extension logs, how to read the Windows enrollment errors Microsoft documents most, and what each remote action (Sync, Collect diagnostics, Retire, Wipe, Delete, Fresh Start) really does. Concepts and vocabulary come from Microsoft Learn; menus move, so confirm in current documentation.
