Configuring preferences and options in Outlook.com
Sorry for the confusion.
The contents of one of the links had the two factor stuff in it.
By the way, I have no idea why your method for the output SMTP works.
Anyhow, problem solved - it just took all day and it was wet and windy and cold here today so nothing much lost - especially at my age :)
Thanks for your help - without you I would not have gone anywhere near Microsoft but the guy was pretty helpful in the chat session. Their AI was useless.
Cheers
