Microsoft will retire its Outlook Lite Android app on May 25, 2026, following its removal from the Google Play Store on October 6, 2025. Launched in 2022 for users in emerging markets, Outlook Lite was designed for devices with 1GB of RAM and slower 2G and 3G networks, offering less storage use and better power efficiency. Microsoft is directing users to its primary Outlook mobile app, which will include an Upgrade option for Outlook Lite users. The primary app is ad-supported, with an ad-free experience available through a Microsoft 365 Personal or Home subscription.
