Anyway, all of my Mac clients just love iCal; I haven't hear of this but a public calendar on a system such as iCal (not really designed for that, but public calendar added as a feature) sounds problematic. I do not use iCal. I use the Office Entourage calendar instead.
I wonder if these spammers have found a way to send out bulk iCal notifications, because it seems like a very inefficient way to send out spam. As I see it, you have to create an event in iCal and then add attendees to be notified. The attendees can be picked up from the Address Book or entered manually, either way seems to be a very time consuming way to spam.
Hi - Tell your colleague to open 'preferences' for iCal, and click on the 'advanced' tab. At the bottom, is a check box that says "automatically retrieve invitations from email" (I'm using the latest version, They may have to poke around to find this checkbox in an older version.). Tell them to uncheck it.
I went and searched the website [macintouch.com ] and found this info in a thread from february 25-27 2008 ( I guess it's a feature, not a bug :)
