Body (from Message Center)

Updated December 2, 2025: We have updated the timeline. Thank you for your patience.

Introduction

Microsoft Edge for Business will soon support Rewrite, a new feature powered by Microsoft 365 Copilot Chat. This capability helps users draft and rephrase editable text directly within Edge, enhancing productivity and writing quality. Users can access Rewrite by highlighting editable text and right-clicking to open the context menu.

This message is associated with Microsoft 365 Roadmap ID 420335.

When this will happen

General Availability (Worldwide): Rollout will begin in late January 2026 (previously early December 2025).

How this affects your organization

Rewrite will be enabled by default for Edge for Business users.
Users can access Rewrite by highlighting editable text and right-clicking to open the context menu.

If Microsoft 365 Copilot is restricted from accessing page content due to Data Loss Prevention (DLP) policies, Rewrite will not function on that content.
Admins can manage this feature using the InlineComposeEnabled policy setting.

What you can do to prepare

No admin action is required before rollout.

We recommend:

Reviewing your current DLP configurations to understand how they may impact Rewrite functionality.
Notifying users about this new capability.
Updating internal documentation to reflect this change.
