The Verge is reporting that Microsoft has released an updated beta version of Outlook for macOS to beta testers in the Fast Ring

Outlook for Mac gets a new design and big performance improvements

Microsoft is bringing some much-needed improvements to its Outlook for Mac app. Starting this week, Outlook for Mac beta testers (in the Fast Ring) will be able to access a new design that comes with some significant performance improvements. Microsoft is bringing its sync technology that’s used on Outlook for iOS and Android and Windows Mail to Outlook for Mac. It means Office 365, Outlook.com, and even Google accounts will sync faster thanks to Microsoft’s cloud services.

Microsoft is also tweaking the design of Outlook for Mac, and adding a lot of features that have been available on the web and mobile versions of Outlook. Reading and writing emails has been improved with single line views, a new mail compose UI, and even features like the ability to ignore emails. Collapsible panels have been added so you can customize the main view of mail and tweak the toolbar accordingly.
