Microsoft has set May 25, 2026 as the cut-off for Outlook Lite on Android, marking the final stretch for the pared-down mail app it’s been phasing out. Past that date, Outlook Lite could still open, but mailbox functions won’t work and users will be nudged to switch over to the primary Outlook Mobile app.
The deadline sets a firm endpoint for users and their IT departments, replacing any lingering uncertainty about when service ends. According to Microsoft’s support page, new installations have been blocked since October 6, 2025, but those who already had the app could continue using it for a short window.
Microsoft’s effort to sunset legacy mail products continues, with the company ending support for Windows Mail and Calendar as of December 31, 2024. Users are being moved over to the new Outlook app or Outlook.com.
Microsoft told Microsoft 365 admins in a new notice that turning off Outlook Lite won’t delete or disable any accounts. All existing emails, calendar entries, and attachments stay accessible via Outlook Mobile. No official admin steps needed, according to the company, but organizations are encouraged to alert users and revise their internal help docs.
So, it’s really more about migration than lost data. On Android, Outlook syncs Gmail, Yahoo, iCloud, and IMAP accounts via Microsoft’s cloud, but Outlook Lite is more limited right now—its support page lists only Microsoft and Google accounts for now, with plans to add more options down the line.
Microsoft introduced Outlook Lite in 2022, targeting users with entry-level Android devices and patchy connections. Pradeep Elavarasan outlined in a company blog post that the goal was “to make Outlook more accessible.” The Lite app, weighing in at around 5 MB, runs on just 1GB of RAM and supports 2G and 3G networks, according to the company.

The app hit a milestone. Back in September 2024, Microsoft reported Outlook Lite had topped 10 million downloads, with features like multi-account support, Gmail integration, and SMS coming onboard through its growth.
Microsoft had already outlined its reasoning ahead of this latest update. Back in September 2025, Windows Latest noted that Microsoft claimed the main Outlook app was now tuned to perform well on lower-end devices, reducing the need for a distinct Lite version as the company trimmed its mobile mail offerings.
But it’s a clear risk. The holdouts on Outlook Lite probably represent exactly the group it was meant to serve — users with older devices, limited storage, or spotty connections — so moving them to the main Outlook app could be rough, despite Microsoft now pitching Outlook Mobile as its main Android email option.
Users have a clear deadline: switch over by May 25 or lose your Lite inbox. For Microsoft, it’s another notch in the steady consolidation of its services, with Outlook folding in yet another legacy product.
