Data Security Investigations introduces new soft purge mitigation action

Microsoft is introducing a new soft purge action in Data Security Investigations (DSI), giving admins a quick and safe way to remove sensitive or overshared files during an investigation. With soft purge, items can be deleted immediately but still recovered later as long as they’re within their deleted‑item retention period, so admins get speed without risking permanent data loss.

This builds on DSI’s growing set of AI‑powered tools like intelligent categorization, AI search, and automated risk insights making it easier than ever for organizations to spot issues and take action fast.

New update coming to Microsoft 365 Roadmap ID 558109. A soft purge action will soon be available in Data Security Investigations (DSI), giving admins a safer and more flexible way to remove sensitive or overshared content during an investigation.

When it’s rolling out

General Availability (Worldwide): Begins early April 2026
Expected completion: late May 2026
