GCC High Priority Update
Week of August 20, 2026
Microsoft Teams is bringing malicious URL protection to GCC High and DoD environments, enabling Teams to detect and warn users when harmful links appear in chat and channel messages. This capability — already available in commercial clouds — closes a meaningful security gap in sovereign environments where phishing and malware attacks delivered through chat links are a real threat vector. Users receive an in-context warning before following a suspicious link, reducing the risk of successful attacks without requiring additional tooling outside of Teams. The feature is currently in development and expected to begin rolling out in October 2026.

Microsoft Purview compliance portal: Insider Risk Management – Microsoft Fabric risk indicators in Insider Risk Management
With this update, Insider Risk Management extends its risk detection capabilities to Microsoft Fabric products by offering ready-to-use risk indicators based on activities that may lead to a data security incident in Power BI. Organizations can use these new indicators in data theft and data leaks policies.
Microsoft Purview Insider Risk Management correlates various signals to identify potential malicious or inadvertent insider risks such as IP theft, data leakage, and security violations. 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.

OneNote: New Copilot Notebooks design in the Microsoft 365 Copilot app (DoD, GCC, GCC High)
The new Copilot Notebooks design in the Microsoft 365 Copilot app for DoD, GCC, and GCC High clouds now lets users organize related chats, output creations, and references into a persistent AI workspace. Copilot uses the Notebook’s accumulated context to ground responses, so work continues across sessions instead of starting over each time. While this is the quicker, light-weight Notebooks experience, you can still find the workspace-forward experience in OneNote.

Microsoft Teams: App centric management in Teams Admin Center to manage the Apps access for tenants, end-users, and groups in GCC High
App centric management introduces new admin settings to control who in the tenant can install Teams apps. First, admins can set a default value for new apps that are published to Teams app store. Second, admins can edit the availability of an app to “All users can install,” “Specific users and groups can install,” or “No user can install.” This feature evolves the existing app permission policies and provides admins with the ability to manage access to the app individually. The app permission policies for existing customers are migrated to maintain existing app availability in the tenant.

OneDrive: PDF annotation for sensitivity-label protected PDFs in the OneDrive apps (iOS and Android)
The Microsoft OneDrive apps for iOS and Android will let users annotate PDFs protected by a Microsoft Purview Information Protection sensitivity label that applies encryption — without removing or weakening the label. Users with edit/annotate rights can add a full set of annotations — including ink, highlight, free text, notes, signatures, image/shape/date stamps, bookmarks, and form fields — directly in the OneDrive mobile PDF viewer; the file’s encryption and usage rights are preserved end to end. This applies to the OneDrive apps for iOS and Android only (not OneDrive or SharePoint on the web). The feature is enabled by default for eligible users and requires no new admin action.

Microsoft Teams: Enhanced live captions settings and right-side panel view
We are improving the live captions experience in Microsoft Teams with new viewing layouts and streamlined configuration options. Users can now view live captions in a new right-side panel, in addition to the existing options of viewing them at the top or bottom of the screen, or popping them out into a separate window.
We are also making it easier to manage caption settings directly within the meeting. By clicking the existing gear icon in the live captions pane, users will see a consolidated menu to quickly configure spoken language, caption styles, and profanity filters without navigating to separate settings panels. Additionally, this menu includes a new toggle to turn on live captions by default for all meetings, as well as a new thumbs-up/thumbs-down feedback mechanism to easily share input on the captioning experience.
