Apparently, these are well know problems with Entourage putting duplicates everywhere. There is even a FAQ topics on “duplicates”:http://www.entourage.mvps.org/faq_topic/duplicates.html thanks to “Joe”:http://bigmountaindesign.com for the pointer. Now maybe I can get rid of the 30 entries for St. Patricks Day in my calendar.
There is a simlar set of utilities of iCal that google:”ical duplicates” and “Hawkwings.net”:http://www.hawkwings.net/2006/05/16/ical-de-dupe-kill-ical-duplicates/ and “John Massey”:http://www.nhoj.co.uk/applescripts/ which has now become a Cocoa application as opposed to just a script. This deduper works like a charm. Wiped out half of the dupes in iCal!!!
For Address Book, there is a builtin deduplicate function and for “Kerio”:http://support.kerio.com/index.php?_m=knowledgebase&amp;amp;amp;_a=viewarticle&amp;amp;amp;kbarticleid=265&amp;amp;amp;nav=0,1,23
