I am using the latest incarnation of Office 360 Outlook with
Icloud 10 for Windows 10.
When I try to create an appointment in my iCloud calendar, outlook
freezes. I know the problem is being caused by the Icloud add-in because I can create
an appointment in my “on this Computer” calendar without issues.
As a further test, I disabled the add in and had no problems
This is happening on two Windows 10 machines I own
