Stop automatically installing the new Outlook

Agreed, I've tried Thunderbird, eM Client and Mailbird, and didn't like or get on with any of them, as I have 4 email address to use, and some only cater for 2.

There was nothing wrong with the old Mail/Calendar app, it started quickly enough was nice and easy to navigate and use, and just worked...

You'd think Microsoft would have got the message (no pun intended) by now few people want this new Outlook, I also have uninstalled it probably about 100 times, yet it keeps invading my pc, I've tried most of the regedit and other work arounds listed here, apart from the really complex batch file stuff as I just don't understand enough about all that, but they just don't work, getting really angry with Outlook now keep forcing it's self on me now.

I have a mail app on my Samsung phone, which is similar to 'old' mail app, but I can't seem to find a way to get that to work on windows.

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?

^ THIS is exactly the problem. As someone said, "they're helping us to migrate". No, they're not. They're forcing us to migrate by using some kind of malware procedure to keep downloading a product I did not ask for or want, despite me constantly checking that I do NOT want to use Outlook, and unstalling Outlook *every* time.

Now I have proceeded to install Mozilla Thunderbird on my 10+ Windows computers. Not overly happy as it certainly runs slower compared to the old Windows e-mail app, but still worlds better than Outlook with the scam ads pushed to the top and idiotic design. Anybody have suggestions for other 3rd party apps that run smoothly even on older hardware? It's certainly a bit of an issue for the slower of the bunch were the old app would open in seconds but Thunderbird takes considerably longer. I wish Apple's e-mail app was available on Windows, that would be awesome. Good, light weight, does nothing but what it's supposed to.

Thanks, but that didn't work, just keeps installing still after .json file removed, and once re-installed adds the .json file back into the same folder.

WHAT A LOAD OF UTTER UTTER B*LLOCKS!!

I know very well how to migrate, as I know how to keep on running Windows Mail AFTER the end date. But I'm not sure that you, in any way, are an experienced user, but probably just an annoying brat.

Your arguments are **** crappy arguments with **** on it, and definitely doesn't hold up.

This has absolutely zero to do with maintenance, but is all about ads, data collection and misunderstood intentions.

They didn't have to kill the app, quite a lot of users are still running Windows Live Mail software on Windows 8, it is not dead.

And making an app/software into a PWA doesn't change maintaining the differences across devices.

Now stop wasting my precious time.
