Summary:
Activity Explorer in Microsoft Purview will default to a 1-day time range instead of 7 days starting May 2026 to improve load performance. Users can still view up to 30 days via filters. No data retention or query capabilities change. No action is required, but inform users of the update.
Details:
[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.
