Microsoft is retiring the Outlook Lite app for Android, with the official end-of-life date set for May 25, 2026. Outlook Lite was introduced in 2022 for smartphones with lower processing power and slower internet connectivity. Microsoft announced the decision to discontinue it back in September, and downloads were halted on October 6 of the previous year. Users are encouraged to transition to the primary Outlook for Android app, which can meet the needs of most users due to improvements in network speeds and device capabilities. An "Upgrade" option is available within the Outlook Lite app to facilitate this transition.
