I've been using icloud calendar for over a year successsfully. Suddenly I can't add any new appointments, or even delete old appointments. What's going on?
I have been using iCloud calendar successfully in Microsoft Outlook for over a year, but suddenly whenever I try to add an appointment, I'm getting a message saying I'm not authorized to do so. I can't even delete old appointments. This just started this afternoon. Any idea what might have happened?
iPhone 4, iOS 5.0.1, icloud
