A new “What’s New” section in the Teams Admin Center will launch worldwide from mid-November to early December 2025. It provides admins with tenant-specific updates, new controls, resources, and Targeted Release visibility. The feature is on by default, requires no setup, and helps admins stay informed and act quickly.
Starting November 10, 2025, Microsoft will remove group-based assignments for Frontier Admin Control access, requiring admins to assign access to individual users only. A transition period from November 6–10 disables changes, converting existing group assignments to user-level entries. Prepare by reviewing and updating assignments accordingly.
A new Copilot icon button provides a quick, visible entry point to Copilot directly within the file previewer in OneDrive. Positioned at the bottom-right corner (instead of the command bar), this button surfaces contextual prompts tailored to the file type and offers seamless access to Copilot chat, making it easier to get insights and take action without leaving the preview experience.
We’re refreshing the Copilot Chat navigation pane to simplify the agents list and increase the visible chat history list beyond a user’s five most recent chats with a more prominent chat history search UI.
This feature will enable Viva Glint Admins to remove survey participants from surveys. The selected survey must have a closed status, and this action will be irreversible.
The floating Copilot button is a quick-access button that appears prominently in your OneDrive web interface. It’s your gateway to Copilot-powered actions —right where you need them. Instant Copilot Access: Ask questions about your files, summarize documents, or compare content—all without leaving OneDrive. Contextual Recommendations: The button will suggest helpful actions based on your file selection—like generating a status report from a file you’ve selected or generating a summary of a new file shared with you. Streamlined Navigation: No more hunting through menus; the Copilot floating button brings the most relevant tools to your fingertips.
Inline protections for text and file uploads, directly integrated into for Edge for Business, can be applied to more unmanaged consumer GenAI apps. Admins can now apply Purview collection policies and Purview DLP policies to detect and protect inline against sensitive data sharing in the Edge browser by users on Intune-managed Windows devices to a selection of new unmanaged app locations.
Starting October 28, 2025, the App Builder agent in Microsoft 365 Copilot will preview via the Frontier program in the US. It enables no-code app creation using natural language, managed by admins through Microsoft 365 Admin Center and Power Platform Admin Center, with apps stored in SharePoint Sites.
