Microsoft is releasing a new smaller and faster Outlook Lite app for Android this week. The lightweight version of Outlook is designed to have a smaller app size, faster performance, and lower battery usage, all while including the core features of the regular Microsoft Outlook mobile app. Outlook Lite is around 5MB in download size, and Microsoft says it “uses extremely low storage on your phone.” It has been optimized to run quickly on all Android devices and even ones with just 1GB of RAM.
