Disappearing Outlook 2002 Calendar Appointments

[Sol]

Under my Outlook 2002 Calendar View, I've noticed that my
recurring appointments and daily appointments were
disappearing from "Day/Week/Month View with
Autopreview." If I switch back to "Outlook Today" view,
all the appointments are there but when I switch back to
Calendar I do not see them.

I also use iPaq PocketPC 1910 to synchronize my
appointments and I do not see all the appointments that
are scheduled for the day.

Where did all my appointments go? Is this a virus or
setting issue?

TIA,
Sol
