Error message: The request for account “iCloud” failed. The server responded with “400” to operation CalDAVUpdateShareesQueuableOperation.

I created a new public iCAL. Trying to send invitations to join and am receiving this error message:


The request for account “iCloud” failed.

The server responded with

“400”

to operation CalDAVUpdateShareesQueuableOperation.


Tried copying the URL link provided for the Calendar into a MailChimp announcement. Not working.

I've tried the uncheck calendar method on iCLOUD and re-checking to stop the pop-up message.


Is this perhaps because they don't have an iCLOUD account? If they have iTUNES, shouldn't it work?


Appreciate any help.
