Microsoft plans to pull the plug on its Outlook Lite app for Android come May 25, ending mailbox access for anyone still using it and pushing users toward the main Outlook Mobile app, per a Microsoft 365 admin notice dated April 10. After the cutoff, users can open the app, but mailbox access, navigation, and nearly all functions inside Outlook Lite are set to stop working.
The clock is ticking for users, with Microsoft nearing the final phase of its shutdown. Just weeks remain to make the switch. Outlook Lite, originally designed for budget Android devices and patchy networks, stopped accepting new installs back on October 6, 2025. Existing users can hang on for now, but only for a short window.
Microsoft says admins can sit tight, but companies should alert staff who still use Lite and refresh their internal help docs. The company noted accounts will stay active, email and calendar content—including attachments—remains accessible on Outlook Mobile, and there’s no change to tenant-wide policies or service access.
On Monday, TechCrunch said Microsoft confirmed it will shut down the service on May 26. But Microsoft’s admin notice actually puts the retirement on May 25, implying the cutoff comes just after that date, not on a separate schedule.
Microsoft rolled out Outlook Lite in 2022, targeting Android users with lightweight phones—think 1GB of RAM and older 2G or 3G connections. The app clocks in at about 5 megabytes. “Our goal is to make Outlook more accessible to users who are on lightweight mobile devices across the world,” wrote Pradeep Elavarasan at launch. Microsoft
Even in its pared-back form, the app managed to draw users. According to a Microsoft blog post from September 2024, Elavarasan said Outlook Lite had “already surpassed 10 million downloads,” underlining that adoption was far from limited to early testers before Microsoft pulled the plug. Microsoft
Microsoft is moving that user base over to Outlook Mobile, calling it its main mobile email app in an admin notice. According to the same update, Outlook Mobile offers compliance features not available in Lite, like Data Loss Prevention—used by software firms to keep sensitive data from slipping outside the company.
So, Microsoft is left without any lightweight mail app on Android—unlike Google, which still provides users with both the main Gmail app and Gmail Go, the slimmed-down alternative for Android. The company’s approach now: pare back its offerings and stick with a single Outlook brand.
There’s a wrinkle here. Folks who chose Lite for its ability to run on 1GB RAM devices and shaky 2G or 3G connections might find the standard Outlook app isn’t quite the same, even though Microsoft insists their accounts and stored emails will transfer. That gap could hit hardest in the very markets Outlook Lite aimed to help.
Microsoft says users have two ways to migrate: either select the Upgrade button within Outlook Lite—if it’s available—or download Microsoft Outlook from Google Play and log in with their current credentials.
