Microsoft Purview eDiscovery: Select user-owned SharePoint Embedded containers as a data source

Microsoft Purview eDiscovery will support selecting user-owned SharePoint Embedded containers as data sources for cases, searches, and holds starting mid-September 2026. This enables discovery of content from Microsoft Loop, Copilot Pages, and Notebooks, enhancing compliance investigations without changing permissions. No admin action is required. Microsoft Purview eDiscovery will support selecting user-owned SharePoint Embedded (SPE) containers when adding a person as a data source in an eDiscovery case, search, or hold.
