MC1144651 - Retirement of Editor Browser Extensions for Microsoft Edge and Google Chrome

Introduction

Microsoft Editor browser extensions for Microsoft Edge and Google Chrome—AI-powered writing assistants offering grammar, spelling, and style suggestions—will be retired and no longer supported after October 31, 2025. This change reflects our ongoing efforts to consolidate writing assistance into the built-in proofing experience in Microsoft Edge.

When this will happen

The Microsoft Editor browser extensions will be retired on October 31, 2025. After this date, they will no longer receive updates or support.

Why this change?

Microsoft Editor extensions have helped users write with clarity, correctness, and confidence. As we continue to evolve our AI capabilities, we are consolidating writing assistance into the built-in proofing tools in Microsoft Edge. This approach simplifies the experience and ensures users benefit from the latest AI-powered enhancements without needing separate installations.

What’s next?

The core capabilities of Microsoft Editor—such as grammar checks and spelling corrections—are now part of the standard Edge experience. This transition will offer:

• Smarter, enhanced suggestions for grammar, spelling, and writing style.
• Seamless built-in proofing experience directly in Edge without requiring additional extensions.

How this affects your organization

• Users who rely on the Microsoft Editor extensions will transition to the built-in capabilities in Microsoft Edge.
• No action is required from administrators.
• Users can continue using the extensions until the retirement date and will automatically benefit from the integrated writing assistance in Edge thereafter.

What you can do to prepare

• We recommend informing users of the upcoming retirement and encouraging them to explore the built-in writing assistance in Microsoft Edge.

We appreciate your continued use of Microsoft 365 and look forward to supporting your writing with even more powerful tools.
