The mail app in windows 10 is broken for me. It worked fine in windows 8, automatically linked all the settings when I transferred my profile across now suddenly all I get is error codes. I can't alter the settings and as it's the account I have linked to my profile it won't let me delete and start again. By not letting me tinker windows have managed to break an app that used to work perfectly well.
