Expanding reference capabilities with Microsoft 365 Copilot in Word [MC1060858]

Message ID: MC1060858

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.

[How this will affect your organization:]

This further extends the richness of grounding support for customers, enabling more complex scenarios with Copilot in Word that support a broader set of customer document and folder reference needs.

[What you need to do to prepare:]

The ability to reference a folder
is available to all Word for the web users and coming to Word for Windows and
Word for Mac users with an Enterprise Copilot license (learn more about
licenses for businesses) in July 2025.

Other capabilities coming later in
April 2025 in Word for the web, Word for Windows, and Word for Mac:

  • The ability to reference up to 20 files when
    drafting a document with Copilot
  • The ability to reference larger files (up to 1.5
    million words or 3,000 pages

You can manage Copilot for specific apps or users through either the Microsoft 365 Admin center or Group Policy.
