About this tag
Microsoft Purview is Microsoft's compliance and data governance platform, and the recent discussions on WindowsForum.com focus on its evolving eDiscovery, Data Loss Prevention (DLP), and security features. Key topics include the upcoming eDiscovery Hold Report for government tenants, Customer Key encryption for direct exports, and the integration of AI-generated DLP alert summaries into Microsoft Defender XDR. Users also discuss the availability of advanced tools like the Review Set Explorer with KQL querying, and the ability to manage Copilot content in eDiscovery. A recurring theme is the discrepancy between Microsoft 365 Roadmap dates and actual preview or general availability, prompting administrators to verify feature statuses before relying on them for compliance workflows.
