Every time I create or send an event in iCal, it sends multiple emails to each attendee (2-3 duplicate emails) with the same event. So if I have 3 event invitees, they get 3 emails each. All the emails are sent from the correct account in Apple Mail, and the calendar itself shows only one email address for each attendee, but for some reason the sent folder shows that each person was emailed 2-3 times. This is causing quite a problem for work, as any invite I send is clogging up inboxes with duplicate and triplicates for each attendee.
When I send a meeting acceptance, it only sends one reply, so I have no idea why it's duplicating or triplicating events when new ones are sent out or udpated by me. I can't delete my calendar without losing important events from clients or what not, so I'm not sure what to do.
I am NOT using iCloud calendars as I needed to create a calendar group and iCloud didn't support that.
My calendar is syncing to an FTP so that people in my main office can view and download my calendar as needed.
I am on a brand new (not even 2 mos old) MacBook Pro Retina 2013 model, with OS X 10.8.3
