Summary:
Microsoft 365 Copilot in Word now allows referencing entire folders, supports larger documents up to 1.5 million words or 3000 pages, and can reference up to 20 items. These features will be generally available by early December 2025. Folder referencing is available now for Word for the web and coming to other platforms in July 2025.

Details:
We heard that customers would like to be able to reference more data, more quickly, when creating, reviewing, and finalizing Word documents using the Draft feature with Copilot in Word. We're happy to share three improvements, developed based on your feedback.
Reference folders when using Copilot: Up until now, when using Copilot, you could reference files, emails, and even meetings, but had to add them one by one. Today, we are enabling you to reference a whole folder (stored on OneDrive or SharePoint).
NOTE: Copilot will use the 10 most recent files as the basis of the content it generates.
Support for larger documents in Word Copilot: We continue to expand the size limits of what we support, and we are expanding our ability to referencing large documents up to 1.5 million words or 3000 pages.
More files can be referenced in Draft with Copilot in Word: You can now reference up to 20 items such as files, emails, and meetings when using the Draft with Copilot command.
[When this will happen:]
General Availability (Worldwide): Rollout has begun and expected to complete by early December 2025.
