Become a Microsoft Purview eDiscovery Ninja


In this blog post, we share the top resources for eDiscovery users to become masters of the Microsoft Purview eDiscovery Premium solution! After each level, we offer you a knowledge check based on the training material you have just completed. The goal of the knowledge checks is to help ensure understanding of the key concepts that were covered. 


The training sessions are split into eight different sections in order to better align with the Electronic Discovery Reference Model:

  • Overview
  • Getting Started
  • Identification
  • Preservation
  • Collection & Processing
  • Review & Analysis
  • Production
  • Advanced

Advanced eDiscovery in Microsoft 365 is now Microsoft Purview eDiscovery Premium! 


Consistent with our One Microsoft philosophy, Microsoft Purview offers a comprehensive set of solutions across information protection, data governance, risk management, and compliance to help organizations govern and protect data across their multicloud, multi-platform data environment, while helping them meet their compliance requirements.


Previously, customers used Azure Purview for unified data governance and Microsoft 365 Compliance solutions to help protect their data and manage risks across their organization. We believe governance and compliance are inherently interrelated data management and business imperatives that should be treated in a unified fashion. That is why we are extending the Purview name and rebranding the combined data governance and compliance platforms to Microsoft Purview.




*This training will be updated on a quarterly basis to ensure you all have the latest and greatest material! 


Microsoft Purview eDiscovery (Premium)

The Microsoft Purview eDiscovery (Premium) solution provides customers with the ability to identify, preserve, collect, process, analyze, review, and produce content that is responsive to your organization's internal and external investigations. Discovering and managing data is challenging. To help solve these challenges, we provide customers with tools that enable them to do more in-place eDiscovery in Microsoft 365, thereby reducing risks associated with either creating multiple copies or exporting content outside of your security and compliance boundaries. Using Microsoft Purview eDiscovery Premium, you can reduce the content and only export matter relevant content.
