I needed to replace the Windows 10 mail app, it stopped showing notifications and microsoft tied ti fix it - for 4 f-ing hours - and couldn’t.
I spent 30 minutes downloading the E m client app, etc. First thing I wanted to do is add my existing yahoo and aol accounts. I could not find a simple way to do that. Your forum had some suggestions but the answers were 5 years old!
I am frustrated and pissed off. I am going to uninstall this app, it is not for normal nontechnical users.
