I just upgraded to Windows10 and am getting the error message shown below in Windows Live Mail for my hotmail account. The Fix-it feature in your Windows 8 KB2842520 article doesn't work in Windows10. I'm afraid to use the "Fix it myself" procedure in regedit as suggested in the article because I don't want to take a chance messing anything up. Do you have a fix for this hotmail problem in Windows 10? Thank you.

"Unable to send or receive messages for the Hotmail (xxxxxx) account.

Server Error: 3204

I've seen this same question re the same error message asked by other people in other forums, but no one has answered them yet.
