Sounds like the association between Outlook and your current .PST file has
been lost and somehow you have an older .PST file open. Search your hard
drive for all .PST files -- and if you're using Windows 2000 or XP, you'll
need to include hidden folders in your search. See if you can't find one
that has a date within the last couple of days and is much larger than the
one you're using now.
