I have been using Outlook 2007 since the beginning of the year. I
just went to look at my past appointments in January and it is empty.
February and the first 2 weeks of March are empty too. It seems like
Outlook 2007 is only keeping the past 8 weeks of calendar data. I
have auto archiving turned off. Does anyone know what the deal is
with this? Is my data gone forever for Jan, Feb and Mar? How can I
prevent this from happening?

Outlook doesn't delete anything from the calendar by itself unless you're
using autoarchive. Do you sync Outlook with any device like a phone or a
PDA?
