GCC High Priority Update
Week of October 1, 2026
Microsoft Purview is introducing a per-policy coverage report for auto-labeling in GCC High and DoD environments, giving admins direct visibility into how files processed during enforcement correlate to the latest simulation run. For each enforced policy, admins can see volumes of labeled and unlabeled files, and identify content that was processed during enforcement but not captured in the prior simulation snapshot. For organizations managing large SharePoint and OneDrive estates under compliance requirements, this report closes the gap between assuming auto-labeling is working and being able to prove it. The feature is currently in development and expected to begin rolling out in November 2026.

Microsoft Purview: Information Protection-Auto-labeling per-policy coverage report
For each enforced auto-labeling policy, admins can view how files processed during enforcement correlate to the latest simulation run. The per-policy coverage report shows volumes of files that have been labeled or are not yet labeled, and whether those files were included in the last simulation snapshot. This helps admins understand enforcement progress for a specific policy against the data state captured during simulation, while also identifying files that were not found in the simulation snapshot but were processed during enforcement.

Power Apps: Control information density in model-driven apps
Model-driven apps now support configurable display density settings that let users choose how information is spaced throughout the application. Users can select from three density options: Comfortable (default) Cozy Compact Each density setting adjusts layout spacing while maintaining accessibility target-size requirements. Administrators and makers can configure default density settings at the environment and app level, while individual users can personalize the experience by selecting their preferred density. User preferences take precedence over administrator-configured defaults. Display density requires the Header and Navigation Refresh experience to be enabled, and will be enabled by default for apps that have Header and Navigation Refresh enabled. Makers can disable display density for their apps using the app setting if needed. Some controls and components may not yet support display density. These controls will continue to render using their standard spacing regardless of the selected density setting. Custom component developers can add support for display density by adopting Fluent design spacing tokens.
