While Android has been a barnstorming success as an open mobile platform, it has still largely been a consumer phenomenon. There are still enterprise IT departments that won't sanction Android devices for employee use, due to purported security concerns, and, in some cases concerns about compatibility with Microsoft's application and messaging platforms.
Now, though, an Outlook Web App (OWA) is going live as a native Android app, which could shut down some of the Android compatibility issues. At the Microsoft Exchange Conference (MEC) in March, officials announced that the company would be bringing a native OWA mobile app to Android phones. The pre-release of this app is now available in the Google Play store.
