Microsoft to Shut Down Outlook Lite Next Month
Microsoft confirmed it will shut down the Outlook Lite app on May 26, 2026. Launched in 2022 as a lightweight Android version of Outlook for low-storage phones and slower networks, Outlook Lite had been slated for removal from the Google Play Store in October 2025. Microsoft told TechCrunch the app will lose functionality for existing users after the May 26 shutdown and recommends switching to the standard Outlook Mobile app. Users can access their existing email, calendar items, and attachments by signing into Outlook Mobile and will be directed to the Google Play Store to download the full Outlook app. The shutdown was first reported by Neowin and is documented on an Outlook Lite support page.
A major vendor (Microsoft) is retiring a consumer app, but the change has limited direct impact on advertising technology or industry monetization channels.
