OUTLOOK - how to remove "new all day event" from Calendar

Using Microsoft Outlook 2000 SR-1- I would like to remove/delete under the
Calendar - the option to create a "new all day event" and "recurring event"
from the drop down list presented - when you right click on a calendar day.

Why: Because when scheduling meetings - the "new all day event" do not
prevent meetings from being scheduled - the user must block out their entire
day 8-5 (new appointment) and must not use the all day event option.
