Microsoft releases guide for collecting Copilot data in eDiscovery searches
Microsoft published a Copilot Data Collection Reference Table for Purview eDiscovery on May 4, 2026. The table maps storage locations for prompts, responses, and other AI content across Exchange, SharePoint, and OneDrive, using item classes such as IPM.SkypeTeams. Message. Copilot.*. It outlines collection strategies for memories, Pages, and facilitator data. Memories fall outside legal holds, and audit logs omit full prompt text, requiring specific Copilot filters for broad searches. The guide addresses the previous gap in handling AI-generated material as Copilot usage grows.
Copilot outputs previously sat in scattered M365 locations without reliable ways for organizations to locate or preserve them during reviews, which kept many teams from relying on the tool for core work. The reference table now provides explicit methods to filter, collect, and export that content, making AI interactions part of the standard, auditable record rather than isolated experiments.
Analysis
This update confirms Copilot outputs are now official M365 content, so dismissing it as a gimmick keeps you stuck in manual triage. Test it today on summarizing one batch of Teams channel updates and save the results straight into your main task list.
