Im trying to get a better understanding of how the calendar invitation works. My email address is at yahoo (on the yahoo account I have only enabled email & contacts) and my calendar is on icloud (I do not have email or contacts enabled on this account). When someone sends me an invitation and I accept, I am not seeing it on either account. I have logged into both webmail accounts and confirm that it is not entered into the calendar. How does this work when your calendar is not on the same account as your email?
