GCC High Priority Update
Week of November 5, 2026
The next generation of Microsoft 365 file and folder sharing is rolling out to GCC, GCC High, and DoD. At the center of the update is the hero link — a single link that controls access to a file regardless of how it is shared, whether copied, sent by email, or taken directly from the browser address bar. The experience is consistent across OneDrive, SharePoint, Excel, Word, and PowerPoint, giving admins and users a predictable, secure-by-default sharing model across the suite.

Insider Risk Management enables customers to create policies based on their own internal policies, governance, and organizational requirements. Built with privacy by design, users are pseudonymized by default, and role-based access controls and audit logs are in place to help ensure user-level privacy.
