Summary:
Starting April 2026, Microsoft Purview Endpoint DLP will enable detection and blocking of egress activities on unsaved files before they're saved, enhancing data loss prevention. This feature is off by default, requires admin setup, and needs devices running anti-malware Client version 4.18.26020 or later.
Details:
[Introduction]
Today, Endpoint Data Loss Prevention (DLP) can only protect content after it's saved to disk. Based on customer feedback and ongoing security investments, we're introducing the ability to detect and block egress activities on unsaved files. This enhancement helps organizations prevent data leakage earlier in the workflow by applying DLP protection before content is written to the device.
This message is associated with Microsoft 365 Roadmap ID 511791.
[When this will happen]
General Availability (Worldwide): We will begin rolling out this feature in early April 2026 and expect to complete by mid‑April 2026.
