[Introduction]
We are improving the Activity Explorer experience in Microsoft Purview to deliver faster load times and a more responsive interface. To optimize performance—especially for organizations with high activity volumes—the default time range will change from 7 days to 1 day when Activity Explorer first loads. This update reflects common investigation patterns where recent activity is most relevant, while preserving full access to historical data through filters.
[When this will happen:]
General Availability (Worldwide): We will begin rolling out in early May 2026 and expect to complete by mid-May 2026.
[How this affects your organization:]
Who is affected: Admins and analysts who use Activity Explorer in Microsoft Purview
What will happen:
- The default view has been updated to 1 day of data to improve performance and load times.
- Users can adjust the date range filter at any time to view up to 30 days (no change from existing support).
- The change is enabled by default for all tenants.
- Improved page load performance and responsiveness, particularly in high-volume environments.
- No changes to:
- Data retention policies
- Query capabilities and filtering options
- Available insights and activity data
[What you can do to prepare:]
No action is required.
We recommend that you:
- Inform admins and investigators that Activity Explorer now defaults to 1 day of data to improve performance.
- Clarify that this is a UI default only and does not affect data availability.
- Remind users they can expand the date range (for example, back to 7 days or more) using the filter when investigating activity.
- Update any internal documentation or training materials that reference the previous 7-day default view.
[Compliance considerations:]
No compliance considerations identified, review as appropriate for your organization.
