"Missing information in order to join" error for Shared Calendars
I have shared Calendars before with various people and they all work flawlessly. Unforunately, one person who I am trying to share a calendar with got a "Missing information in order to join" error message when she tries to join. I have no idea why this is happening. She has a hotmail email address. Any idea/suggestions as to why this could be happening?
I am using a 4S, she is using a 4.
