Microsoft has announced the retirement of its Outlook Lite app for Android, effective May 25, 2026. After this date, Outlook Lite will no longer provide access to mailboxes, and users will need to transition to the Outlook Mobile app to access emails, calendars, and attachments. New downloads of Outlook Lite have been halted since October 2025. Microsoft is consolidating its mobile strategy around the Outlook Mobile app to enhance compliance and integration with Microsoft 365 services. Users are advised to upgrade to Outlook Mobile through the Play Store or manually download it, ensuring they sign in with the same account to restore access to their data. IT administrators do not need to take special actions but should update internal documentation to guide employees toward Outlook Mobile.
