Duplicate and deleted U.S. Holidays catigories

[laustrup]

I am having a problem when I sync entourage with my PDA. Every time I
sync, I get another duplicate holiday entry in my calender. I tried
using the help instructions that led me to advanced search/ find to
delete duplicates, but it showed NO RESULTS! I was trying to delete
the duplicates when I accidentally deleted the entire Holidays-US
category. Does anyone know how to get rid of duplicate entries, as
well as, restore my Holidays-U.S catigory????

Thank you
