(Updated) Open PDFs within Copilot [MC1223823]

Message ID: MC1223823 (Updated)

Updated April 23, 2026: We have updated the timeline. Thank you for your patience. 

Introduction

Microsoft is improving the reading and review experience in Microsoft 365 Copilot by enabling PDFs to open directly within Copilot when users click them. This update streamlines content access and reduces context switching based on customer feedback.

When this will happen:

General Availability (Worldwide): Rollout will begin in mid-April 2026 (previously mid-February) and is expected to complete by early May 2026 (previously late February).

How this affects your organization:

   Who is affected:

• All Microsoft 365 users who interact with PDFs in Microsoft 365 Copilot.
• A Microsoft 365 Copilot license is required to use this feature.

   What will happen:

• Users who click a PDF inside Copilot will have it open directly within the Copilot interface.
• The feature is enabled by default for all tenants.
• No admin configuration changes are required.
• Existing Purview policies for PDFs continue to apply.

What you can do to prepare:

• No action is required from administrators.
• Optionally notify helpdesk/support teams of the updated PDF experience.
• Update internal documentation if it describes Copilot PDF behavior.

Compliance considerations:

No compliance considerations identified, review as appropriate for your organization.
