Microsoft 365 Copilot: Discover Copilot actions in OneDrive/SharePoint file preview

Originally posted by Microsoft Apr 16, 2026 Uncategorized 0 Comments

Starting late April 2026, Microsoft 365 Copilot will show suggested actions like summarizing and FAQ generation directly in OneDrive and SharePoint file previews. Enabled by default for eligible users, this feature respects existing permissions and policies, requiring no admin action but user awareness is recommended.

Introduction

We are improving how users discover Microsoft 365 Copilot capabilities in the file previewer of OneDrive and SharePoint. Ready to use Copilot actions will appear directly in the file preview experience, alongside the Copilot button. When users preview supported files, suggested prompts will help them complete common tasks such as summarizing documents, generating FAQ, and extracting key information without writing their own prompts.

When this will happen

General Availability (Worldwide): We will begin rolling out in late April 2026 and expect to complete the rollout by early May 2026.

• Suggested actions may include summarizing content, generating FAQ, and identifying key points.
• The feature will be enabled by default for eligible users. Suggestions will disappear after a timeout or after a user interacts with a file.
• Existing Copilot, OneDrive, SharePoint, and Microsoft Purview policies will continue to apply.
• There will be no change to file permissions, sharing behavior, or data residency. Copilot will continue to respect existing access controls and Microsoft Purview policies.

What you can do to prepare

• No admin action is required.
• Consider notifying users that Copilot suggestions will appear in OneDrive file previews to support awareness and adoption.
• If Copilot is disabled or restricted in your tenant, those settings continue to apply.
