Updated August 27, 2026: We are removing this message as it is a duplicate of MC1461154. Please refer to MC1461154 for any updates moving forward. We apologize for any confusion. What and why We're increasing the maximum auto-labeling capacity for Microsoft Purview Information Protection in SharePoint and OneDrive from 100,000 files to 500,000 files per tenant per day. This enhancement enables organizations to automatically label and protect a larger volume of existing content more quickly, helping reduce labeling gaps across data stored in SharePoint and OneDrive. By applying sensitivity labels and associated protection settings to more files each day, organizations can strengthen their information protection posture and better prepare their data estate for Microsoft 365 Copilot. This message is associated with Microsoft 365 Roadmap ID 567890. Rollout schedule Public Preview: Beginning in early September 2026 and expected to complete by late September 2026 General Availability (Worldwide): Beginning in early October 2026 and expected to complete by late October 2026 Impact on your organization Who is affected Organizations using Microsoft Purview auto-labeling policies that target SharePoint and OneDrive content Platforms and services Microsoft Purview Information Protection SharePoint Online OneDrive for Business What will happen The maximum auto-labeling capacity for SharePoint and OneDrive will increase from 100,000 files to 500,000 files per tenant per day. Existing active server-side auto-labeling policies targeting SharePoint and OneDrive will automatically benefit from the increased capacity. More content can be evaluated, labeled, and protected each day without requiring policy changes. No change to label configuration, policy behavior, or user experience is expected as part of this update. Action required and recommendations No action is required. To maximize the benefit of the increased capacity, we recommend that administrators: Create an auto-labeling policy for SharePoint and/or OneDrive in simulation mode. Review simulation results after processing completes. Enable the policy if the results meet your organization's requirements. Monitor labeling activity through the Policy activity overview and the Auto-labeling coverage report in Microsoft Purview.
