The beta has some stringent restrictions, however, that may be extended to the full release. You must be running Android 4.4 (or newer), your device cannot be larger than 5.2-inches (sorry no tablets or the Galaxy Note) and your mailbox must be running on Office 365 for business.
As with most betas, the new OWA release in its current form will be to help the company collect feedback, fix bugs and improve stability.
Currently, there are just a few devices that have access to the app, but you can vote to have your device added via this link here: OWA for Android Pre-Release.
Microsoft launched OWA for iOS about a year ago, and promises the Android version will have all the same features.
