Windows 10 mail app ready to go button inactive

I used to use Windows Live Mail 2012 but up until about a week ago, it stopped syncing my hotmail account. I got an email in May or June about upgrading to a new program or something that was taking place in July I believe, but it kept working so I didn't do anything.

Now WLM does not sync my hotmail account, so I tried using the Windows 10 mail app. I added several different email addresses, but the ready to go button always stays inactive. I googled the problem and found a solution on the MSFT website, but it does not work. What else should I try.....you do not appear to be able to uninstall the mail app.

Is it possible to uninstall the mail app and reinstall it?

You can still use WLMail with a hotmail account using imap & smtp rather than deltasync.
Incoming Server name:
imap-mail.outlook.com
Port:993
Encryption method: SSL
Outgoing Server name:
smtp-mail.outlook.com
Port:587
Encryption method: SSL
Usually the mail app will automatically enter the details & set up the account, you just enter your hotmail email address & password, is the problem occurring after doing this?

No, I never tried to continue using WLM....I am guessing that if I set the hotmail account up with the new W10 mail app with these settings it would probably work correctly.

These settings do appear to work with WLM though so I will continue to use it. I had to delete the account then make a new one, checking the manual config checkbox. Thanks
