Summary

Microsoft Edge for Business will support Microsoft 365 Copilot Chat to summarize and provide context from browser tabs, Microsoft 365 documents, and YouTube videos starting mid-November 2025. The feature is off by default, respects DLP and policy settings, and requires Entra ID sign-in and appropriate licensing.

More information

Introduction:

Microsoft Edge for Business will soon support summarization and contextual grounding with Microsoft 365 Copilot Chat. This enhancement enables users to ask Copilot questions about multiple open browser tabs, Microsoft 365 documents (such as Word, Excel, PowerPoint), and YouTube videos directly from the Edge side pane.

This message is associated with Microsoft 365 Roadmap ID 496364, 499423, and 499424.

When this will happen:

General Availability (Worldwide): We will begin rolling out in mid-November 2025 and expect to complete by late November 2025.

How this affects your organization:

Who is affected: Users signed in to Microsoft Edge for Business with their Entra ID and who have access to Microsoft 365 Copilot.

What will happen:

  • Users will be able to ask Copilot questions about open browser tabs, Microsoft 365 documents, and YouTube videos.
  • The feature will be off by default.
  • If Copilot is restricted from accessing page content via Data Loss Prevention (DLP) or the EdgeEntraCopilotPageContext policy, it will be suppressed to maintain DLP integrity.
  • Existing DLP and policy configurations will be respected.

What you can do to prepare:

  • This rollout will happen automatically by the specified date; no admin action is required before rollout.
  • Ensure users who need this capability have access to Microsoft 365 Copilot.
  • Ensure your tenant is configured to support Microsoft 365 Copilot and that eligible users meet all licensing prerequisites, including Entra ID sign-in and applicable Microsoft 365 service plans.
  • Review your current DLP and Edge policy configurations to determine potential impact.
  • Notify users about this upcoming capability.
  • Update internal documentation if needed.

Compliance considerations:

QuestionAnswer
Does the change introduce or significantly modify AI/ML or agent capabilities that interact with or provide access to customer data?Yes. Microsoft 365 Copilot introduces contextual grounding and summarization using generative AI across browser tabs, Microsoft 365 documents, and YouTube videos.
Does the change provide end users any new way of interacting with generative AI?Yes. Users can now ask Copilot questions about open browser tabs and documents directly from the Edge sidepane, enabling real-time summarization and contextual responses.
Does the change modify Data Loss Prevention (DLP) policies or enforcement?Yes. If DLP or the EdgeEntraCopilotPageContext policy restricts access, Copilot will be suppressed from accessing page content to maintain DLP integrity.
Does the change include an admin control, and can it be controlled through Entra ID group membership?Yes. Admins can manage access to Copilot’s contextual grounding capabilities via DLP settings and Edge policy configurations, which can be scoped using Entra ID group membership.
