Not able to delete calendar event in iPhone I'm facing this issue that i have accepted a friend's invitation for call and it got added as a calendar event in my iPhone. Now the issue is when i'm opening it, there i'm unable to find the edit button from which i can delete this event from the calendar.

Has anyone faced similar issue like this. Any help is appreciated.
I removed the mail account from the device and then added it again. By doing this i was able to remove those events from iPhone calendar.
