Microsoft Purview eDiscovery review
A Microsoft 365-focused eDiscovery suite with legal holds, case management, and review tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Microsoft Purview eDiscovery helps organizations preserve, search, collect, review, analyze, and export Microsoft 365 data for legal, compliance, and regulatory investigations. It is designed for teams managing matters across Exchange Online, OneDrive for Business, SharePoint, Microsoft Teams, Microsoft 365 Groups, Viva Engage, and selected AI application data. Case management brings searches, legal holds, and review sets together, while custodian tools support data-source association and hold communications.
The published plan is Microsoft Purview Suite at $12 per user per month billed annually. The plan includes Microsoft Purview eDiscovery and broader Purview data security and compliance capabilities. It requires Microsoft 365 E3, or Office 365 E3 and Enterprise Mobility + Security E3. That makes the pricing easier to assess for organizations already working within those Microsoft licensing arrangements, while teams outside that ecosystem should account for the required licensing structure.
Its strongest fit is for matters that need structured hold administration and a review workflow in the Microsoft 365 environment. Custodian acknowledgment tracking, automated reminders and escalations, audit logging, review-set search and filtering, tagging, analytics, predictive coding, relevance prioritization, and export support a broad eDiscovery process. Teams seeking a Microsoft 365-centered system with these capabilities should consider it; organizations needing a platform built around non-Microsoft content locations or a separate licensing model should look elsewhere.
