iCloud sends messages for every change in someone else's calendar
I am trying to use iCloud calendar services for collaboration with my wife, and my secretary (I actually even bought a mac for my wife so that we could do this).
However every time either of them change anything in their respective calendars I get an e-mail from iCloud saying an event has been created. This only started about a week ago.
I have checked to see if some of my settings in iCloud have changed, and they haven't (the box in iCloud that says: "E-mail me when this calendar changes" is not ticked).
I am now totally confused about why I am suddenly getting all these e-mails which are quite irritating.
