Microsoft Purview | eDiscovery – Metadata field enhancements in process reporting [MC1162273]

[Introduction:]

To improve transparency and streamline post-export workflows, Microsoft Purview eDiscovery is enhancing metadata reporting in the item.csv files generated during Add to Review Set and Export processes. These updates are designed to provide deeper insights into item-level attributes and improve error traceability.

This message is associated with Microsoft 365 Roadmap ID 506220.

[When this will happen:]

• General Availability (Worldwide, GCC, GCCH, DoD): Rollout will begin in early October 2025 and is expected to complete by mid-November 2025.

[How this affects your organization:]

Who is affected: Admins and users working with Microsoft Purview eDiscovery (Standard and Premium) workflows, particularly those who rely on metadata exports for review and automation.

What will happen:

• The item.csv report will have the follow updates:
  • Status: Indicates if the item is processed successfully or has errors.
  • Error Detail: Detailed error messages for the item.
  • Custodian: SMTP address of the custodian the item was associated with.
  • Sensitivity label: GUID of the sensitivity label applied to the item.
  • IsEncrypted: True or false value to indicate if the item is encrypted.
  • SharePoint Item Content Type ID: Hexadecimal value representing the SharePoint content type.
• Admins will continue to have access to reports generated prior to this update. Newly generated reports will include the updated metadata fields and structure.
• These changes will enhance visibility into item-level processing and support downstream automation and auditing.

[What you can do to prepare:]

• Review and update internal documentation to reflect the new field names and structure in the item.csv report.
• Adjust automation or post-export workflows to rely on field names rather than fixed column positions.
• Communicate these changes to relevant compliance and legal teams.
