Mac Email
Whenever I attempt to send an e-mail I get a request box headed 'outlook.com' saying ''unable to verify account name or password'. This has only started in the last couple of days.
Also. I get the same message when I attempt to create a new e-mail account.
My software version is Catalina
What do I need to do to fix this? I am not a computer wizard.
