Ammon News - Microsoft is set to shut down an Outlook app that has been downloaded by more than 10 million users tomorrow.

Outlook Lite, which launched in 2022, is an app for Android devices, bringing users all the Outlook essentials in a smaller size.

It was made for low-resource phones and has the ability to work on slower networks.

Outlook Lite was retired by Microsoft on October 6, 2025, with the app removed from the Google Play Store.

Despite the app being retired, existing customers have still been able to use the app until now.

When will Outlook Lite be fully retired?
Microsoft has confirmed the Outlook Lite app will be shut down on all Android devices on Monday (May 25).

The app will still open after it has been fully retired, but mailbox access will be disabled, and in-app navigation and functionality won't work.

Microsoft said: "The Outlook Lite app will be fully retired and will no longer provide mailbox functionality starting May 25, 2026.

"To continue enjoying a secure and feature-rich email experience, we recommend switching to Outlook Mobile. Go to Outlook for iOS and Android for more information."
