Microsoft is expanding Microsoft Purview Endpoint Data Loss Prevention on macOS with enhanced content extraction and significantly broader file type coverage. This update increases the number of supported file types from approximately 40 to more than 100, bringing Mac endpoint DLP protection in line with coverage already available across Exchange, SharePoint, and OneDrive. By improving classification and protection of sensitive data on Mac devices, this enhancement strengthens compliance and data protection consistency across the enterprise. The feature is currently in development and is expected to begin rolling out worldwide for standard multi-tenant environments in January 2026.

Microsoft is expanding Microsoft 365 Copilot’s mobile capabilities with voice notes, allowing users to capture offline conversations and turn them into structured, searchable, and actionable content. With a Microsoft 365 Copilot license, users will be able to record voice notes directly in the Copilot mobile app and later revisit key takeaways, summaries, and insights. This feature is currently in development and is expected to begin rolling out worldwide for standard multi-tenant environments in January 2026.

Microsoft is improving trust in Microsoft 365 Copilot with deep citations, which link generated responses directly to the exact section of source content. Launching first for Word and PowerPoint, this update will help users quickly verify accuracy and reuse AI-generated content with confidence, especially important for governed and compliance-focused environments. Support for meetings, web content, and PDFs will follow, with worldwide standard multi-tenant rollout planned for February 2026.

Managing AI agents in the enterprise is evolving. Microsoft is expanding Purview Insider Risk Management to include AI agents, introducing dedicated risk indicators and scoring based on agent activity. This enhancement helps organizations detect and address insider risks, such as data leakage or security violations, while maintaining privacy. The update will begin rolling out in January 2026 for standard multi-tenant, GCC, GCC High, and DoD customers.

Working with Copilot is getting even easier. Microsoft is rolling out a feature that ensures conversations are preserved even when users navigate away from a session. As soon as a prompt is submitted, an entry is immediately created in the navigation pane’s session history allowing for a quick return without losing progress. The update is rolling out now for standard multi-tenant, GCC, GCC High, and DoD customers.

Administrators using the Microsoft 365 admin center and Teams admin center who manage agents and apps that work across Teams, Outlook and the Microsoft 365 copilot will be able to apply their changes consistently across all these surfaces.

Finally, Interpreter settings have also been improved with concise explanations for each configuration and field, making setup easier and minimizing confusion. These updates are expected to rollout in December 2025.

Microsoft is bringing Copilot Chat to the core Microsoft 365 apps across Commercial, GCC, GCC High, and DoD environments.

The update reflects Microsoft’s continued investment in making Copilot broadly accessible, including for government customers. Initial rollouts are expected to begin as early as December 2025, with additional environments following in early 2026.
