[Introduction]
We're introducing Phase 2 of always-on diagnostics for Endpoint Data Loss Prevention (DLP). This update enables admins to collect diagnostic traces directly from Windows endpoints and upload them to Microsoft through the Purview portal during support investigations-without involving the employee or information worker . This improves troubleshooting efficiency and helps resolve support cases faster.
This message is associated with Microsoft 365 Roadmap ID 499431.
[When this will happen]
General Availability (Worldwide): We will begin rolling out in early March 20265 and expect to complete by mid-March 2026.
