I have a MacBook Pro and prefer to use Outlook than Apple's rubbish Mail app. For a month or so now, every couple of weeks or every week the Microsoft Outlook app asks me for the account password. Having generated an app password and saved it to my passwords it doesn't recognise it, I then have to generate a new password which works for a bit then seems to stop working a couple of weeks later. It's getting a bit annoying. It won't let me use the 'master' passowrd for the sky account.
