Microsoft Purview's toolset for finding, preserving, reviewing, and exporting content for legal cases and investigations.
eDiscovery in Microsoft Purview is the toolset for finding, preserving, reviewing, and exporting Microsoft 365 content for legal cases, regulatory requests, and internal investigations. Searches span Exchange mailboxes, SharePoint sites, OneDrive accounts, Teams chats and channels, and Viva Engage. Two tiers: eDiscovery (Standard) included with E3, providing content search, hold, and basic export; and eDiscovery (Premium) included with E5, adding custodian management, conversation reconstruction, predictive coding, near-duplicate detection, advanced review-set workflows, and Cloud Attached eDiscovery integration with platforms like Relativity. Replaced older Exchange-specific In-Place eDiscovery. Per-user eDiscovery licences may apply for Premium scenarios.
