> Outlook is the lone exception where that team decided to have Outlook for the web, Windows Outlook, and Mac Outlook be identical, so those are getting their rewrites with removal of Win32-specific features where applicable.

I wish they didn't. Outlook on macOS is abysmal nowadays and I still find myself resorting to the legacy view just to change some settings that both iterations can read but only one exposes.

I significantly prefer using Thunderbird or the web views for Gmail and Zoho Mail over any version of Outlook. Is the integration across O365 apps nice? Sure, but the platforms themselves are miserable to use.

In a similar vein, I was cautiously optimistic about Teams V2 for unifying the client. But then they completely dropped the Linux client for their PWA which does not have feature parity with the "native" platforms and has a significantly worse UX.
