Hi - this is probably an obvious one but I'd appreciate some help

I keep all our outlook appointments for the last 4 years as we need to
constantly refer back. They are displayed in the yearview interface (a
simple year viewer skin by Planet Software).

A couple of days ago all appointments over 6 months old disappeared
(except recurring appointments)

Checked in tools/options/folders/autoarchive and found that it was set
to run every 14 days and clean out items over 6 months old. I've
opened up archive.pst but the the calender appears only to be 6 months
old as well.

Any idea is it is really an archive problem I am looking at and how to
retreve them.

Finally I have an old pst which will have the lost items - can I
import a date range from this ?

Thanks
