About this tag
Sensitivity labels in Microsoft Purview Information Protection are central to Microsoft 365 data governance, classification, and compliance. Recent updates expand label support to Viva Engage communities, Teams meeting recordings, and Office for the web with user-defined permissions. New controls allow administrators to target label policies more precisely using modern groups and dynamic security groups. Purview now offers sync status for label publishing policies, improving visibility into propagation. Endpoint DLP can detect sensitivity labels inside ZIP archives, closing an enforcement gap. Additionally, sensitivity labels can block Microsoft 365 Copilot from analyzing labeled content, reinforcing AI governance. These changes reflect Microsoft's ongoing effort to make classification travel with data across storage, collaboration, and AI services.
