Summary:
Microsoft Purview introduces a File Quarantine action for SharePoint and OneDrive DLP policies, isolating violating files in an admin-controlled quarantine site with a tombstone placeholder. Rolling out mid-April to June 2026, it requires admin configuration, manual restore, and enhances data protection and compliance monitoring.
Details:
[Introduction]
We are introducing the File Quarantine action in Microsoft Purview Data Loss Prevention (DLP) for SharePoint and OneDrive to help organizations better protect sensitive data. When a file violates a Purview DLP policy, it can be automatically isolated to prevent further access or sharing, allowing administrators to review and take appropriate action. This capability adds an additional layer of protection against accidental data exposure while supporting everyday collaboration.
This message is associated with Microsoft 365 Roadmap ID 557190.

Public Preview: Rolling out in mid-April 2026 and expected to complete by early May 2026
