Describe the eDiscovery solutions in Microsoft Purview
Electronic discovery, or eDiscovery, is the process of identifying and delivering electronic information that can be used as evidence in legal cases. You can use eDiscovery tools in Microsoft Purview to search for content in Exchange Online, OneDrive for Business, SharePoint Online, Microsoft Teams, Microsoft 365 Groups, and Yammer teams. You can search mailboxes and sites in the same eDiscovery search, and then export the search results. You can use eDiscovery cases to identify, hold, and export content found in mailboxes and sites.
Microsoft Purview provides three eDiscovery solutions: Content search, eDiscovery (Standard), and eDiscovery (Premium).
Content Search. Use the Content search tool to search for content across Microsoft 365 data sources and then export the search results to a local computer.
eDiscovery (Standard). The eDiscovery (Standard) solution builds on the basic search and export functionality of Content search by enabling you to create eDiscovery cases and assign eDiscovery managers to specific cases. The eDiscovery (Standard) solution also lets you associate searches and exports with a case and lets you place an eDiscovery hold on content locations relevant to the case.
eDiscovery (Premium). The eDiscovery (Premium) solution builds on the existing capabilities in eDiscovery (Standard). In addition, eDiscovery (Premium) provides an end-to-end workflow to identify, preserve, collect, review, analyze, and export content that's responsive to your organization's internal and external investigations. It lets legal teams manage custodians, people that you've identified as people of interest in the case, and the workflow to communicate with custodians. It allows you to collect and copy data into review sets, where you can filter, search, and tag content so you can identify and focus on content that's most relevant. The eDiscovery (Premium) solution provides analytics and machine learning-based predictive coding models to further narrow the scope of your investigation to the most relevant content.
Subscriptions that support eDiscovery (Standard) also support Content search. Subscriptions that support eDiscovery (Premium) also support Content search and eDiscovery (Standard).
