Major Update – Complete retirement of the Outlook Lite app – Action needs to be taken

Hi All,

Greetings. LIFE IS BEAUTIFUL 🙂

Today, I am sharing a MAJOR UPDATE related to the Outlook Lite app.

Major Update: Complete retirement of the Outlook Lite app

Details

• Microsoft will complete the retirement of the Microsoft Outlook Lite app on Android on May 25, 2026.
• Outlook Lite will be retired as part of Microsoft’s broader effort to reduce overlap and focus development and support on Microsoft Outlook Mobile.
• After this change, Outlook Lite will no longer provide functional access to mailbox features.

Timelines

• October 6, 2025: New installations of the Outlook Lite app were blocked.
• May 25, 2026: Outlook Lite will be fully retired and will no longer provide mailbox functionality for existing users.

Important Points

• User accounts will not be deleted or disabled
• All existing email, calendar items, and attachments will remain accessible when users sign in to Microsoft Outlook Mobile.
• This change does not affect tenant‑level configurations, policies, or service availability.

Action we need to perform in our Organization

• Notify users who may still be using Outlook Lite about the upcoming retirement.
• Encourage users to install and sign in to Microsoft Outlook Mobile
• Update internal documentation or helpdesk guidance if Outlook Lite is referenced.

Recommended alternative: Microsoft Outlook Mobile

Users can switch by

• Selecting the Upgrade option in the Outlook Lite app (if available), or
• Opening the Google Play Store, searching for Microsoft Outlook, installing the app, and signing in with existing credentials.
