When I set up an all-day event, Outlook has always shown it as a banner in
the days involved with no times and crossing multiple days (in the monthly
view) - the way it is supposed to. Now it displays all-day events like a
regular appointment without a banner and with the time always being 12 AM and
only in the first day of a multiple day event.

How can I get it back to the banner look that crosses multiple days?

I am using Outlook 2003 with SP2.
Thanks.
