Outlook Lite for Android brings Microsoft's email app to budget phones
 

Specifically, Microsoft says that Outlook Lite has all the main features of the Outlook experience neatly packed into a 5MB app that's optimized for speed, even on lower-end Android devices. The company says the app was designed to run fast on devices with as little as 1GB of RAM, use less battery impact than the full app and offer good performance on older 2G and 3G networks.
