💡 Our Technical Review in summary
Microsoft is updating the metadata reporting structure for Microsoft Purview eDiscovery (Standard and Premium). The enhancement focuses on the `item.csv` files generated during the “Add to Review Set” and “Export” processes. This update aims to provide IT admins and legal teams with better transparency, improved error traceability, and more granular item-level attributes to streamline downstream workflows.
#### Impact
The rollout, beginning in early October 2025 and concluding by mid-November 2025, will introduce several new fields to the `item.csv` report:
- Status: Clear indication of whether an item was processed successfully or encountered an error.
- Error Detail: Specific error messages to assist in troubleshooting failed items.
- Custodian: The SMTP address of the custodian associated with the specific item.
- Sensitivity label: The unique GUID of any Microsoft Purview Information Protection label applied to the item.
- IsEncrypted: A boolean value (True/False) indicating the encryption status of the item.
- SharePoint Item Content Type ID: The hexadecimal value representing the specific SharePoint content type.
Existing reports generated prior to this update will remain unchanged, but all newly generated reports will follow the updated schema.
#### Action Required
To ensure a smooth transition and maintain the integrity of eDiscovery workflows, IT admins should take the following steps:
- Update Automation Scripts: If your organization uses scripts or third-party tools to parse `item.csv` files, ensure they are configured to reference field names rather than fixed column positions, as the structure of the CSV will change.
- Revise Internal Documentation: Update any internal SOPs or training materials used by the legal and compliance teams to include descriptions of the new metadata fields.
- Stakeholder Notification: Inform compliance officers and legal departments about the enhanced reporting capabilities, specifically the improved visibility into encryption and processing errors.
- Review Reporting Workflows: Evaluate how the new fields (such as Sensitivity Label GUIDs or Custodian SMTP) can be used to improve post-export data handling or auditing.
