MC1223826Open Outlook emails directly in Copilot chat

Updated April 29, 2026: We have updated the timeline. Thank you for your patience. 

Introduction

We’re introducing a new capability that enables users to open Outlook emails directly within any full‑app Microsoft 365 Copilot experience, including Copilot chat. This enhancement helps reduce context switching by allowing users to view referenced emails alongside their Copilot interaction.

When this will happen:

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

How this affects your organization:

Who is affected:

• All users who access Microsoft 365 Copilot full‑app experiences, including Copilot chat.

What will happen:

• Users will be able to open Outlook emails directly from references or sources shown in Copilot chat.
• Emails will open side‑by‑side within the Copilot experience.
• The feature is enabled by default.
• Existing Microsoft 365 permissions and data access models remain unchanged.
• No changes are made to Outlook, Exchange Online, or Copilot admin controls.

What you can do to prepare:

• No administrator action is required.
• Update internal documentation if needed.

Compliance considerations:

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