I find that when I create appointments over a year ahead (and show
the time as "Busy") the date is not highlighted in the calendar,
although more imminent dates are highlighted. (Also, some past
entries are not highlighted, despite being entered as "Busy", which
makes it hard to look for past appointments by inspection.)

What are the rules governing highlighting and can they be altered by
the user, or is my copy of Outlook 2003 simply malfunctioning?

Ten months into the future and two months into the past are the rules
governing the bolding in the Date Navigator.
