I recently upgraded my iPhone 4 to a 4s and swapped the 4 for my wife's 3GS. At the same time I changed our Mobile me accounts to iClouds. We both run shared calendars that I created and shared whilst on mobile me. Since the changes, every time I update one of the two calendars my wife gets an email telling her of the update and this is starting to Amoy her. Funny thing is I don't get an email when she updates one of the calendars. Any suggestions on how I can turn off these emails?
