I have 6 email accounts that I run within Windows Live Mail. All are working OK apart from my outlook.com account which gives the above error code. This started this morning.

I have tried the fixit which did not work, the regedit fix does not seem to apply to Windows 10 which I am using. I finally tried deleting the account and when I try to reinstall it within Windows Live Mail I still get the same error code when it tries to synchronise the account.
