Hi No sync,

I'm sorry to hear you are having these issues with iCloud on your Windows machine. If you continue to have issues with iCloud and Outlook, you may find the information and troubleshooting steps outlined in the following article helpful:

I found this article below.

For me, simply signing out of iCloud (removing all data from my PC) and signing back in again seems to have done the trick!

We'll see if it's a permanent fix!!
