Purview eDiscovery partner enabled functionality:

eDiscovery professionals who need to access, process and export ESI from Microsoft 365 from their favorite eDiscovery platform should understand the capabilities and limitations of the Graph eDiscovery API used by authorized third-party applications to connect to Microsoft Purview eDiscovery (Premium). This API integration or custom internal PowerShell driven applications can perform tasks such as creating cases, custodians, holds, searches, and exports. This allows customers to leverage Microsoft Purview’s functionality via your preferred eDiscovery software and workflows. The chart below presents the core eDiscovery API functions. The eDiscovery API is currently in beta and is evolving rapidly.
