Outlook 2000 from the Office 2000 Professional suite.

I was thinking about migrating my DayTimer stuff to Outlook (which I had
never used), so I entered some recurring holidays - 20 of them. Then just to
check to be sure I had done it correctly, I exported those out to a .csv
file. Of the 20 items entered, only 14 were exported. I went back and checked
to see what I had fat-fingered, but Outlook correctly shows the non-exported
items as holidays. Knowing about how Outlook doesn't export recurring items
as such, I did another export - this time with a date range from 1/1/2009 to
12/31/2050. Some (not all) of the missing items started to appear, but not as
expected. For example, Thanksgiving Day had been entered as a yearly
recurring holiday for the fourth Thursday in November, starting 11/26/2009.
The export listed these dates for Thanksgiving:

11/22/12
11/23/17
11/22/18
11/23/23
11/23/28
11/22/29
11/23/34
11/22/35
11/22/40
11/23/45
11/22/46

While those are the correct dates, there's obviously quite a few missing.

Any ideas as to what might be happening? I don't want to spend a lot of time
and effort migrating to Outlook if it's not going to be possible to reliably
export stuff out of it.

Thanks

Kurt
