Microsoft will retire Outlook Lite for Android on May 25, 2026, after which users will no longer be able to access emails through the app. New downloads of Outlook Lite ceased in October 2025. Users will be guided to transition to the full Outlook app, and their accounts and data will remain intact. Outlook Lite was designed for low-end devices and had over 10 million downloads in its first year but struggled in the market. The trend of phasing out Lite applications is seen as a response to improved smartphone capabilities and internet connectivity. Users have just over a month to transition before the official retirement of Outlook Lite.
