MC1294523 - Microsoft Edge: M365 Copilot Search relevance using work browsing history

Introduction

With IT administrator approval, Microsoft Edge will share selected work browsing history from Microsoft and third‑party apps with Microsoft 365 Copilot Search to improve search result ranking. When users search in Microsoft 365 Copilot Search, Copilot will surface previously visited work pages more quickly, helping reduce time spent re‑finding information. Admins will control availability through a Microsoft Edge policy, and browsing history will be shared only when Microsoft 365 Copilot Search is configured in the Microsoft 365 admin center.

This message is associated with Microsoft 365 Roadmap ID 537283.

When this will happen

General Availability (Worldwide): We will begin rolling out in early May 2026 and expect to complete by mid-May 2026.

How this affects your organization

Who is affected

• Organizations using Microsoft Edge for Business
• Tenants with Microsoft 365 Copilot Search configured in the Microsoft 365 admin center
• Admins managing Microsoft Edge and Microsoft 365 Copilot policies
• Users signed in to Microsoft Edge with a work account

There will be no change for consumer Microsoft Edge users or personal browsing profiles.

What will happen

• If enabled by administrators, Microsoft Edge will share selected work‑related browsing history with Microsoft 365 Copilot Search to improve search result ranking.
• Eligible browsing history will include pages from administrator‑configured Microsoft and third‑party work apps and sites.
• Browsing history will be collected only from Microsoft Edge work profiles.
• Personal browsing profiles and consumer Microsoft Edge users will not be included.
• A user‑visible setting will appear in Microsoft Edge under Settings > Microsoft 365 Copilot, allowing users to turn the feature off when permitted by admin policy.
• If the ShareBrowsingHistoryWithCopilotSearchAllowed policy is disabled, no browsing history will be shared.

What you can do to prepare:

• Review and configure the ShareBrowsingHistoryWithCopilotSearchAllowed Microsoft Edge policy to align with your organization’s privacy and compliance requirements.
• Coordinate with Microsoft 365 Copilot administrators to ensure consistent Copilot Search behavior across your tenant.
• Notify security, privacy, and helpdesk teams about the upcoming capability and the user‑visible Edge setting.
