Microsoft’s Outlook Lite Android App Will Stop Working on May 25

Microsoft’s Outlook Lite Android app will be fully retired on May 25, 2026, the company announced on its Microsoft 365 Admin Center (via Neowin). The app had already been pulled from the Google Play Store in October (The app will disappear from the Google Play Store on October 6, 2025), and Microsoft now recommends Android users to its main Outlook mobile app.

Outlook Lite initially launched back in 2022, and it was designed for users in emerging markets with phones with just 1GB of RAM and on slower 2G and 3G networks. Compared to the main Outlook mobile app, Outlook Lite uses less storage and is more power efficient, and it also integrates SMS messages.

The retirement of Outlook Lite is part of a “broader effort to reduce overlap and focus development and support on Microsoft Outlook Mobile, our primary mobile email experience,” Microsoft explained. Outlook Lite didn’t integrate cloud services and Microsoft’s Copilot AI, and it also didn’t support enterprise features such as Data Loss Prevention (DLP).

If you’re still using Outlook Lite, you should see an Upgrade option that will guide you through the installation of the main Outlook Mobile app. This app is ad-supported, just like the Windows version, and you’ll need a Microsoft 365 Personal or Home subscription to get an ad-free experience.
