Microsoft Outlook for iOS and Android: Clearer Copilot availability in multi-account experiences

What and Why We're updating Outlook for iOS and Android so the Copilot button more clearly reflects when Copilot chat is available for users with multiple accounts connected to the app. The Copilot button will appear in multi-account views (unified message list and calendar) if at least one connected account supports Copilot chat. It will be hidden in single-account views where Copilot chat is not supported. This change does not affect Copilot eligibility, licensing, or feature availability; it is a UI update that better reflects existing support. This change improves clarity and helps users better understand when Copilot is available. It does not change Copilot eligibility, licensing, or feature availability. Rollout Schedule General Availability (Worldwide, GCC, GCC High, and DoD): Beginning in early July 2026 and expected to complete by late July 2026.
