OUTLOOK365

On my MacBook Pro I need to switch from Mail and Calendar, contacts etc. to Outlook365, for the mail adresses no problem, however my calendar contacts, reminders etc are in iCloud.

Creation of an email in outlook in the following way didn't workout:

Add email adress=> I took my Apple ID => provider iCloud=> generated 3rd partie password

without success as outlook doesn't recognise the combination, what do I do wrong ?
