Microsoft is retiring the Outlook Lite app for Android in October 2025, starting with new users/downloads. Existing users can continue using the app for a limited time before it is fully retired.
The Outlook Lite app is a streamlined version of Outlook, designed for Android devices with limited storage, RAM, or older hardware. It provides the essential Outlook experience with minimal resource usage.
The retirement aligns with ongoing investment in the standard Outlook Mobile app on Android, which provides broader functionality, security, and manageability.
- Organizations are affected only if users currently rely on Outlook Lite.
- After retirement begins, new installations will no longer be available from the Google Play Store.
- Note that Outlook Lite has never been available for iOS devices.
Timeline
- Retirement for new users: Monday, 6 October 2025 (new installations)
- Retirement for existing users: A few months after retirement for new users
How does this affect your users?
To maintain a secure and feature-rich email experience on Android, users should switch to the standard Outlook Mobile app. Migration is seamless and uses existing credentials. No manual steps are required, and mail, attachments, and calendar data remain accessible after signing in.
Users will receive a notification prompting them to install the Outlook Mobile app.
- From an Outlook Lite notification, select the Install Microsoft Outlook banner, or open the Google Play Store, search for the Outlook Mobile app, then download and install it.
- Sign in with your existing credentials to access email, calendar, and files.
