Requesting help in re-adding iCloud to Office 365 Outlook Classic on my PC. (Not online Outlook)

Adding iCloud to Windows 365 Outlook Classic

I use Outlook Classic on my Windows 11 PC. I use iCloud to sync my calendar and contacts between my Windows PC and my iPhone 15Pro. All was working well and then it wasn't.

I followed the tip - uninstall iCloud for Windows from MS Outlook.

I can see calendar and contacts on iCloud but I cannot get to sync with Outlook Classic on my PC.

Tips are welcome! Thanks!!
