In our office, we share an Outlook calendar to schedule time off for
about 80 employees. The problem we have run into is that once you go
over a certain about of entries on one day for the Calendar it hides
the information. So if we are looking at the Calendar for a particular
day there may be entries that we cannot see. I've played around with
this and if you start deleting other items on that same day the hidden
ones suddenly appear.

Has anyone experienced this problem with Outlook? Is there a fix for
this? One note that may be important is that we enter everything as an
all day event so that it will show in a stacked format. In addition,
we use the view "day/week/month with auto preview".
