Updated September 12, 2025: We have updated the timeline. Thank you for your patience.

Introduction

Outlook Mobile is introducing a new Copilot Chat overlay experience for iOS and Android devices. This enhancement allows users to interact with Copilot while continuing to use their email, calendar, and contacts. The overlay is context-aware, enabling users to ask Copilot questions about the content currently on their screen. Users with Microsoft 365 Copilot licenses will benefit from richer, personalized responses powered by Microsoft 365 Graph.

When this will happen

General Availability (Worldwide, GCC, GCCH, and DoD): We will begin rolling out in ~~early~~late September 2025 (previously early September) and expect to complete by early March 2026.

How this affects your organization

Once rolled out, all users will receive the new Copilot Chat overlay experience in Outlook Mobile by default. This update does not change Copilot Chat availability at the organization or user level. Existing licensing and admin controls remain unchanged.
