Introduction
We’re making changes to modern eDiscovery Content Search case. Starting February 16, 2026, Content Search cases will no longer support review sets or case-level data sources. These capabilities will remain available in dedicated non-Content Search eDiscovery cases.
When this will happen
This change will begin rolling out on February 16, 2026.
How this affects your organization
Who is affected: Organizations using eDiscovery Content Search case in Microsoft Purview.
What will happen:
- Users may notice that review sets and case-level data source options are no longer available in the Content Search case when this change is implemented.
- Users who require review, filtering, tagging, analytics, or other advanced review capabilities may no longer be able to perform these actions in Content Search case after this change.
- Existing searches and direct exports in Content Search cases will not be affected.
What you can do to prepare
- No action is required if you use Content Search cases only for search and direct export.
- We recommend users move review activities to dedicated eDiscovery cases for investigations that are not Content Search cases.
- If your workflow requires review sets or case-level data sources:
- Create a separate eDiscovery case for investigations.
- Add data sources and review sets in that case to continue your end-to-end eDiscovery workflow.
