It will take a little work to remove the dupes, but here is a shortcut:
In the calendar, click view \ current view \ by category. This will produce
a table of your calendar items grouped by category. All the holidays will be
in a "Holiday category."

You will need to multiselect the items to duplicate. Remember the CONTROL
key pressed when clicking the item to select.

I accidentally added the holidays multiple times to Outlook 07. Is there
anyway to delete them at one time or do I have to go through each holiday and
delete it one at a time?
