Using New Outlook on Windows for professional communication and productivity
Good morning Brian,
I figured it out.
So you are right. With the new Outlook - you have to add the iCloud account. It's bit tricky though.
Mail -> View -> View Settings -> Accounts -> Add Account -> Use your iCloud account email, not your iCloud login email -> create app password in apple id portal -> input app password in outlook -> then it will connect.
I use Gmail for my apple id and it kept wanting to add my Gmail account. You have to use the iCloud email given to you by apple to make this work.

Thanks again!
