Original Title: windows live mail

I am going crazy on our computer since my husband added windows 10 with windows live mail.  I have like 3 email accounts listed which I would like to all erase and start over.  I keep getting error 0x800ccc0e.  I would like to totally remove windows live mail and start right from the beginning.  Please help with the easiest way to do this? When we look for uninstall program we don't see windows live mail but part of it is somewhere in our computer and giving us this error and problems receiving and sending?
