Windows isn’t going to die as long as those features aren’t in the enterprise. The Outlook version they discuss is the one bundled with Windows 11 which enterprises don’t use since they use the one that comes with their E3 license and part of Office 365. And all the “telemetry” bloat is disabled in Windows 11 Enterprise. And enterprises are where they make the most money. So as long as “I use it at work and it’s what I know” prevails, then they won’t lose a large market share. (Not to mention Linix is still too complicated for 99% of users too)

The good Outlook is being replaced for MS365 corporate too in a couple of years.
