Introduction

We're introducing a new preview experience in the Microsoft 365 Copilot app for Android that allows users to open Word, Excel, and PowerPoint files and interact with them using Copilot Chat. For editing actions, the Microsoft 365 Copilot app will transition to the fully featured standalone Word, Excel, or PowerPoint apps. This change positions Microsoft 365 Copilot as your AI-first productivity assistant, bringing together activity across Word, Excel, PowerPoint, Outlook, and other Microsoft 365 apps.

This message is associated with Microsoft 365 Roadmap ID 518290.

When this will happen

  • Mid-November 2025: Users may begin seeing prompts to install the standalone Word, Excel, or PowerPoint apps when attempting to edit those file types in Copilot.
  • Mid-December 2025 – End of January 2026: Previewer experience rollout begins and is expected to complete by end of January 2026 (previously mid-January).

How this affects your organization

Who is affected:

  • All users of the Microsoft 365 Copilot app on Android.
  • Tenant admins responsible for app deployment and mobile productivity.

What will happen:

  • Copilot Preview Experience: Users can open Word, Excel, and PowerPoint files in the Copilot app on Android and use Copilot Chat for summaries and insights.
  • Editing Files: Editing will require switching to the standalone Word, Excel, or PowerPoint apps. Users will be prompted to install or open these apps.
  • Teams, OneDrive, Outlook app integration: These apps on Android will continue to show users previews of Office files. Editing will redirect users to the respective standalone apps. The Microsoft 365 Copilot app will no longer handle file open and edit operations from Teams, OneDrive or Outlook.
  • File Management: File search remains available in Copilot. Advanced management will require the standalone OneDrive app.
  • Document creation: Users can create documents via chat in Copilot. Viewing remains in-app; editing transitions to standalone apps.
  • Offline access: Offline viewing will only be available in the standalone Word, Excel, PowerPoint, and OneDrive apps. “Make Available Offline” is being removed from Copilot.
  • PDF workflows: No changes; PDF handling continues as before.
  • Folder browsing: Folder browsing from OneDrive, SharePoint, or third-party hosts will no longer be supported in Copilot.
  • Protocol URLs: Opening documents via protocol URLs will require the standalone apps.
  • Third-Party hosts: Adding third-party host accounts to Copilot will no longer be supported.

What you can do to prepare

Tenant admins should:

  • Plan deployment of the standalone Word, Excel, and PowerPoint apps to support file editing.
  • Deploy the standalone OneDrive app to enable file and library management.
  • Communicate to users that editing and template creation will require switching to standalone apps.
  • Update internal documentation to reflect this workflow change.
