MC1182707New Copilot button in file previewer for OneDrive and SharePoint

Updated December 12, 2025: We have updated the timeline. We will not be rolling out this feature to GCC, GCCH and DoD customers at this time. We apologize for the inconvenience. 

Introduction

We've added a new Copilot button that gives users a quick and visible entry point to Copilot directly within the file previewer in OneDrive and SharePoint. This button appears near the bottom-right corner of the file previewer (instead of in the command bar) and surfaces contextual prompts for Copilot-supported file types. It also provides access to the Copilot chat. This feature will be available to users with a paid Copilot license

This message is associated with Roadmap ID 513432.
