This was one of the most outrageous data grab in the past years. They replaced the completely working simple Mail app, which I used until that point, with this garbage, and I was just lucky that I paid attention, and I stopped for a sec what is that warning which tells you that they grab literally all of your emails.
Btw, just before that I found this page regarding Edge, and this is why I paid more attention to these things:

That list is way too long for my taste, and it really indicated me that Windows became completely adversarial.
