More information
Updated April 6, 2026: We have updated the timeline. Thank you for your patience.
Introduction
We’re adding a new soft purge mitigation action in Data Security Investigations (DSI) to help administrators quickly remove sensitive or overshared items during an investigation. Soft purge allows items to be deleted while remaining recoverable until their deleted item retention period expires. This addition builds on DSI’s AI-powered content analysis capabilities—such as categorization, AI search, and risk examination—to help organizations identify and respond to data security risks more efficiently.
This message is associated with Microsoft 365 Roadmap ID 558109.
