Integration of AI-Powered Proofing Tools
The Editor extensions will be officially deprecated on Fri, Oct 31, 2025, as part of Microsoft’s strategy to integrate AI-powered writing assistance directly into the native proofing tools of Edge. Key features such as real-time syntax parsing, context-aware style checks, and AI-driven rewrite suggestions will be embedded within Edge’s proofing engine. This change is designed to streamline deployment for IT administrators and end users without requiring changes to settings or Group Policy Objects (GPOs).
The integration is supported by Azure OpenAI, offering enhanced suggestions without the latency or compatibility issues associated with browser add-ons. Microsoft 365’s built-in proofing tools will automatically assume the functionality previously provided by the extensions.

After October 31, 2025, the Microsoft Editor extensions will no longer receive updates or support and will cease functioning. Administrators are not required to deploy updates or disable settings as the built-in proofing tool in Edge will take over all Editor functionalities.
Users can continue using the Editor-Edge and Editor-Chrome extensions until the retirement date. Afterward, grammar checks, spell correction, and style suggestions will be accessible from Edge’s settings under “Languages and proofreading.”
Organizations utilizing Microsoft Purview for activity logging may need to adjust their monitoring policies as extension-specific telemetry will be integrated into broader browser logs. Users are encouraged to become familiar with Edge’s new proofing UI, which includes configurable options for AI-driven suggestions, dictionaries, and change history reviews.
