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.
