alt Hacker NewsWhich "new" Outlook? I think there's like 3 versions of Outlook currently on the market. The Classic Win32 one they want you to stop using, the new Lite variant bundled for free with Windows 11, and the new Full Spec one that comes with Office 365, both of which are built on web technologies IIRC.
That one that comes with office 365. My work PC got auto updated with it and I switched back to the Win32 version within an hour because it was buggy and a huge resource hog. It's just an email client and calendar, there's no need to keep reinventing the wheel, especially if you're just gonna make it worse.
The macOS version still has all of them beat.
