Rolling out worldwide from March 2026, it requires admin enablement and does not affect existing DLP policies.
Starting mid-April 2026, Always-on diagnostics for Endpoint DLP will be enabled by default on Windows devices, storing diagnostic logs locally for 90 days to aid troubleshooting. Admins can opt out anytime via Microsoft Purview. This improves issue resolution but may affect investigation efficiency if disabled.
