Microsoft Outlook is the American firm’s email client that replaced Hotmail in 2012.
The software is available on desktops in addition to Android and iOS smartphones via an app.
Outlook for computers received a huge redesign last year that not only modernised the look of the software, but also added new features such as an improved search bar.
Since the upgrade for desktops, Microsoft has announced the iOS app for the client would receive a similar overhaul.
Discussed back in December, the new software supports sensory feedback, touts a fresh aesthetic and a new animated calendar icon.
Speaking about the new application, Jon Friedman, the Chief Designer of Office, said: “Great experiences are felt as much as they are seen. When we craft them, we pay attention to the details that make Outlook mobile feel faster.
“With the new design in Outlook for iOS, we’re introducing new sensory feedback to create a resonant experience with the device cradled in your hand. When you swipe right or left on an email, subtle changes in colour, shape, and iconography unfold.
“The corners of the message transform from hard-edged to soft and round, metaphorically pulling that item away from the message list and sending it where you want it to go—with haptic feedback.”
Moreover, Friedman discussed the need to create a “consistent” experience for users on mobile.
He went on: “The first thing most will notice as we roll out the Outlook for iOS changes over the next few weeks is the bold colour that creates a more vibrant experience. We recognise that people use many apps on their devices and quickly switch between apps to complete tasks.
“A strong app header with bold colour and typography helps you easily find your way to Outlook while rapidly switching between monochromatic apps to quickly complete your task and get back to what matters.
“The experience is consistent across mobile email, search, and calendar; and for those who use Outlook on a large screen, the blue header connects you to your familiar inbox and calendar no matter which Outlook you use.”
When Microsoft first announced the new version of Outlook for iOS it was initially only available for beta testers.
However, Outlook’s head of product for iOS, Michael Palermiti, has now confirmed the new version of the app is available for all iPhone fans.
Announcing the news on Twitter, he wrote: “As of today the rollout of the new Outlook for iOS design is now available to all users!
“Thank you for all of the feedback, keep it coming!”
Users that already have the Outlook app installed should have received an update bringing the new changes.
Those that do not have the software can get it from the App Store.
