Last July, Microsoft released an iOS app specifically designed to replicate the features of its Outlook Web Access (OWA) browser-based interface, but in a native iOS environment for business Office 365 users. This week, it has announced plans to do the same for Android, saying a native app will be available soon.
It's possible to read Office 365 email in the built-in Android email client, but the OWA options adds support for additional features such as rights management. The move comes just a week after a full-blown Office suite for iPad was released, though that suite doesn't include Outlook or OWA. No fixed release date yet, but we're assuming this will appear sooner rather than later.
