Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Terry,
If you are trying to setup the iCloud account on the Outlook application, you may need to use the app password instead of the regular password.
To generate the app password for your iCloud, you can go to this link: https://appleid.apple.com/account/manage
Once done, use that on the Outlook app and it should allow the account to be configured.
