Prevent/Fix: Microsoft Purview | Activity Explorer – Total count includes duplicate results

Microsoft Purview’s Activity Explorer will update its UI to show “Total results loaded” instead of “Total count” to avoid confusion from duplicate counts. Exported data remains deduplicated and unchanged. No data loss or performance impact occurs. No user action is needed, but informing compliance teams is recommended. Introduction We’re improving how totals are displayed in Activity Explorer to reduce confusion and improve trust in exported results. Today, the total count shown in the Activity Explorer UI can appear higher than the number of records exported due to duplicate records being included in the UI count. While exported data already removes duplicates and maintains full data integrity, this discrepancy can give the impression that data is lost during export. To address this, we’re updating the UI to display a more accurate count based on results currently loaded in the portal. When this will happen:We will begin rolling out this change in an upcoming service update. We will update this post once rollout timing is finalized. How this affects your organization: Who is affected: Microsoft 365 administrators and compliance teams using Activity Explorer in Microsoft Purview. What will happen: The “Total count” shown in Activity Explorer will be replaced with “Total results loaded.” The displayed number will reflect the count of events currently loaded in the portal view. Exported data remains unchanged and continues to include only unique records. There is no data loss and no change to export deduplication behavior. This approach avoids performance impact for large tenants. What you can do to prepare:No action is required. We recommend informing compliance teams about the updated label and updating any internal documentation that references the Activity Explorer total count. Compliance considerations:This change affects how counts are displayed in the Activity Explorer UI but does not change how customer data is stored, exported, or retained. Message ID: MC1251201
