iCloud on Windows enabled for only Calendar and Contacts

I have a prior version of Office (2016) and it's always been a solid functioning software....so I've been aways dancing around forced updates. Latest Office update foiled me....and iCloud was crippled as well as my Office version updated to Microsoft 365!!

Worked with Microsoft several days getting Office (2016) back in place and healthy....BUT.. I lost access to iCloud synching with my contacts / email & calendar!!

I've always used Apple via iCloud for managing my contacts and calendar.

I've been downloading iCloud from the Microsoft Store....

based on other blogs and issues encountered have attempted a number of options...

including: Sign out of or uninstall iCloud for Windows - Apple Support (PH)

Set up iCloud Calendars and Contacts in Outlook on your Windows computer - Apple Support (PH)

If you can’t add iCloud Mail, Contacts, or Calendars to Outlook - Apple Support

Latest issue is, I just reinstalled iCloud for Windows maybe 10th or 12th time....

Check my Programs and Features....there is NO Apple software installed and YES...I sorted by Publisher??!!

YET...when I rebooted...and attempted to turn on iCloud (YES iCloud is running even though NOT installed??!!)....it allowed me to enable Calendars and Contacts...I then received:

Outlook Setup Error

!Your setup couldn't be started because of an unexpected error. (0x80070057)

Error: 0x80070057: CalDAV URL is empty.

I know this sounds unbelievable; so I performed a Full screen shot via Snipping Tool supporting my statements above!
