After 10.14.4 my hotmail and ntlworld mail accounts will not login. Have checked passwords and theses are the same ones that still work on the iPad and iPhone . But re-entering on iMac says "unable to verify account name or password". The question "mail for mac will not accept my password" has an answer about "app-specific passwords" and talks about 2-level authentication . What should I do ? Do I have to make new passwords for hotmail and ntlworld? Or is there a bug fix coming? Help!!!!
I assume you are using Apple Mail to collect your mail?
One solution that seems to work for many is to delete these accounts entirely then go to Sys Prefs > Internet Accounts and re-establish/enter them. That's why I did and it worked just fine for me (and for others).
