I've recently migrated my contacts from Palm Desktop to Outlook 2003 by first
exporting to a CSV file and then importing into Outlook. I noticed that not
all of my contacts with entries in the birthday field showed up in my Outlook
calendar.

My first thought was the formatting (missing year) was the problem, so I bit
the bullet and put in the year for those contacts without year entries for
their birthdays in the CSV files and re-imported. However this did not fix
the problem.

Anyone have any ideas on what I did wrong or how I can fix this problem?
