Stop automatically installing the new Outlook

So I've accepted the fact that they're killing the Mail app the day after tomorrow. I'm still not installing the new (nor the old) Outlook on my computer and will only use the online version when strictly needed. For now I'm fine with the generic Email app on my phone to check my mails. To the people at Microsoft that took this decision, I wish you the worst and hereby I cast a curse to you and the next three generations of your offspring.

But I wanted to stop getting replies from this thread, and when I finally found that the solution is to actually Subscribe (to the question I never subscribed to in the first place) THEN unsubscribe, I finally understood the whole joke that Microsoft really is.

Thanks for nothing!

And to my fellow Mail app advocates, my heart goes out to you, I wish you a happy (yet mail-less) new year ♥

The source code excuse makes no sense. If different branches of source code were such a problem, you'd want as many people to move across as possible, as quickly as possible.

Baking scam ads and a subscription into your new platform does not make people want to switch, it makes them want to stay on the old platform, and if you force the switch, it'll make them migrate to a competitor. Nobody wants an email client that delivers fake emails.

The Windows Mail app will stop receiving and sending email after December 31, 2024.

Of course it is the source code because microsoft is moving corporate enterprise customers to the new outlook app by 2029. One source code base for all 5 platforms.

Ok, sure it's the source code, and absolutely nothing to do with the fact their new app is pushing scam ads to the top of my inbox disguised as emails, and selling a subscription to remove them.

I paid for a copy of windows, part of that purchase was the mail app. I want to continue using the app I already paid for, not the new app that wants to charge me to solve a problem Microsoft created.

The way it functions now, I have to manually uninstall the Outlook (New) app every single time I want to open the old mail app, so to return to the topic at hand. As this is my computer, and not Microsofts, how do I stop this so I can use the software I want to use?

Microsoft made it easy for people to just migrate to their new app.

If you don't like their new app, then learn how to migrate to a 3rd party app yourself. But it is YOUR choice to migrate to another 3rd party app because you DON'T like their new offering.

Microsoft killed the windows mail app because they were maintaining 5 completely different source code (outlook for desktop windows/mac/mobile/web and windows mail app). They want to maintain a single source code which is good for the long run. Even large enterprise customers have to migrate by 2029.
