Microsoft has revealed a suite of changes to its Outlook email client, both the Office application and Outlook.com webmail service, with the aim of making it easier and more intuitive to use.

The Outlook application for Windows, which comes as part of Microsoft Office, will soon feature a more streamlined Ribbon interface. For anyone who's used Outlook and been frustrated by the cluttered Ribbon bar that often hides useful tools and features when you need them (we’re talking from experience here), this will be a welcome move.
