file quarantine

The file quarantine tag covers Microsoft Purview File Quarantine for SharePoint Online and OneDrive for Business. The featured guidance recommends piloting the capability before broad deployment, particularly where organizations can reliably classify sensitive files and support manual restoration. Quarantine removes matched files from their working locations, creating operational considerations beyond conventional DLP blocking. Restoring access may require rebuilding permissions, sharing links, and business access. The discussion also notes Microsoft Purview’s mid-2026 general availability timeline after public preview and presents conventional DLP blocking as the safer production control for organizations that are not prepared to manage quarantine and recovery processes.
