Ask: Bonjour,
J'ai intégré l'appareil Windows 10 avec la stratégie DLP Endpoint, mais celle-ci apparait avec l'état de synchronisation de la stratégie DLP "Non disponible".
Vous trouvez ci-joint les informations concernant les détails de cet appareil ,inclut le système d'exploitation, la version du moteur Defender ,la version du rapport d'analyse de l'agent MDE Client Analyzer.




Solution: Unfortunately, despite following the troubleshooting steps you provided, the issue persists. The DLP Endpoint policy synchronization on my Windows 10 device continues to display as "Not Available."
I have verified the device onboarding status, licensing, configuration settings, and policy parameters as suggested. Given that these checks did not resolve the problem, I may need additional support or insights into the technical root cause.
If I missed anything please let me know and I'd be happy to add it to my answer, or feel free to comment below with any additional information.
If you have any other questions, please let me know. Thank you again for your time and patience throughout this issue.
