Hi @Yuta WAKITA
I understand you're specifically asking about Activity Explorer in Microsoft Purview Information Protection rather than general audit logs. Let me break it down for you:> Licensing Requirement for Activity Explorer
To access Activity Explorer in Microsoft Purview (Data Classification), you need a Microsoft 365 E5 license.
- Microsoft 365 E5 includes all the necessary capabilities for Microsoft Information Protection (MIP) and Activity Explorer.
- Microsoft 365 E3 does not provide access to Activity Explorer, as it lacks the required data classification and protection insights.
Activity Explorer allows you to
Track labeling activities – See who labeled, relabeled, or removed labels from files.
Monitor file protection actions – View events related to encryption and classification policies applied to content.
Export data – You can filter and export the activity logs as a CSV file for further analysis.
For more details, you can refer to Microsoft’s official documentation:
- Microsoft Purview service description
- Get started with activity explorer
- Learn about auditing solutions in Microsoft Purview
Hope this helps! Let me know if you need further clarification.
