Microsoft to Discontinue Outlook Lite App for Android by May 2026

Microsoft will discontinue the Outlook Lite app for Android on May 25, 2026. The company will end all mailbox access on that date, requiring users to switch to the Outlook Mobile app. After May 25, users can open Outlook Lite, but they will not be able to access emails, calendars, or attachments.

Key Highlights

• Microsoft will discontinue Outlook Lite for Android on May 25, 2026
• Users will lose access to emails, calendars, and attachments after the shutdown date
• Outlook Lite stopped accepting new downloads from October 6, 2025
• Microsoft recommends migrating to Outlook Mobile for continued email access

End of Outlook Lite Support

Microsoft created Outlook Lite for Android users with entry-level smartphones or limited network connectivity. The app offered a lightweight alternative for those who needed basic email features. However, Microsoft will now focus on the more advanced Outlook Mobile app, which supports a wider range of mailboxes and offers better compliance features.

Microsoft blocked new downloads of Outlook Lite from October 6, 2025. This move aimed to prevent new users from joining the platform before its shutdown. The company confirmed that the app will not function after May 25, 2026, and users must migrate to Outlook Mobile for continued access.

Migration to Outlook Mobile

Microsoft recommends that current Outlook Lite users switch to Outlook Mobile. The Upgrade option within Outlook Lite will direct users to the Google Play Store to download Outlook Mobile. Users can also manually install the app and sign in with their existing accounts. This process will restore access to all emails, calendar items, and attachments.

The Outlook Mobile app offers deeper integration with Microsoft 365 services. It provides broader mailbox support and improved compliance features compared to Outlook Lite. Microsoft assures users that their accounts will not be deleted or disabled during the transition.

Guidance for Users and IT Administrators

Microsoft advises users to migrate before the shutdown date to avoid losing access to their data. The company also recommends that IT administrators update internal documentation and guide employees to switch to Outlook Mobile. No special actions are required from IT teams, but proactive communication can help prevent disruptions.

Outlook Lite was only available for Android devices. There is no dedicated Outlook Lite app for iOS. Microsoft’s decision to end Outlook Lite reflects its strategy to consolidate mobile email services under one app with more features and better support.
