Microsoft is shutting down Outlook Lite on Android and pushing users to the full Outlook app — a move that raises questions about Microsoft’s long‑term mobile strategy

Microsoft is officially retiring Outlook Lite on Android on May 25, 2026, ending support for the lightweight email client designed for low‑end devices and slower networks. The company is directing users to transition to the full Outlook app, which now serves as Microsoft’s single mobile email experience.

While Microsoft says the main app has improved enough to replace Lite, the change raises concerns for users who relied on the smaller footprint and faster performance. The move also signals a broader consolidation of Microsoft’s mobile strategy as it focuses on a unified Outlook experience across platforms.
