Body (from Message Center)

Updated May 7, 2026: We have updated the timeline. Thank you for your patience.

[Introduction]

We are introducing a refreshed chat‑first design in the Microsoft 365 Copilot mobile app. This update modernizes the interface and streamlines navigation to make it faster and easier for users to start, continue, and manage chats. The improved experience is based on customer feedback and aligns the mobile app more closely with the broader Copilot visual design. The updated design will release first on iOS, followed shortly by Android.

[When this will happen]

Public Preview: Rolling out in mid-May 2026 (previously late April) and expected to complete in late June 2026.
