Amazon took its enterprise-aimed email and calendaring service called WorkMail out of preview mode.

WorkMail integrates with Microsoft Outlook, Apple Mail and other email clients that use the Microsoft Exchange ActiveSync protocol including iPhone, iPad, Kindle Fire, Fire Phone, Android, Windows Phone and BlackBerry 10.
