We are running Outlook 2007. A user mistakenly added an appointment to a wrong user's shared calendar. After realizing her mistake, she attempted to delete said recurring appointment but was prompted with the error: "Some items cannot be deleted. They were either moved or already deleted, or access was denied". This particular user has full permissions to edit, add, delete, etc. appointments off of said shared calendar, but is unable to delete this particular recurring appointment.
Any ideas on this?
