Can't connect iCloud/iPhone calendar with New Outlook

I would like to connect and sync my iPhone 14/iCloud Calendar with MS 365 New Outlook. I was able to sync the calendars using Windows 10 and Classic Outlook.

This week, I upgraded to Windows 11 and New Outlook. I can't even see an option for connecting my iPhone Calendar with New Outlook. In New Outlook, when I go to Settings/Email Account/Add Account, I try to enter my email, and the error message says "This email account has already been added."

Where do I go from here?

Thanks,

Sam
