Microsoft’s mobile roadmap for e-mail changed significantly in 2015 with the release of new Outlook for iOS and Android applications. The Outlook for Android application calendar is shown here.

Outlook for iOS and Android applications are based on technology acquired with Acompli in Nov. 2014. The applications have replaced Outlook Web App for Devices, a line of applications for iPhone, iPad, and Android applications that were previously Microsoft’s favored enterprise mobile mail clients. Microsoft also promotes Outlook for iOS and Android over native Exchange Active Sync mobile mail clients from Apple and Google.

Outlook for iOS and Android receive frequent improvements. Improvements rolling out or likely in 2017 include the following:

A new data center architecture that keeps all user data in Exchange Online mailboxes and that tracks individual IDs for connecting devices. This avoids some security and compliance objections to the previous architecture, which stored cached mailbox data in Amazon Web services and kept only per-user connection information.
