Can't change default alarm period in Outlook 2007

I am running Windows Vista Home Premium with Outlook 2007 on Toshiba laptop.
I cannot change the default alarm period in the calendar from the 18 hours
that is currently the default. I have gone to "tools" chose properties and
there it has a default reminder box under preferences/calendar.When I change
the time frame, hit apply and ok, and close, it remains as 18 hours, however
the time frame I changed it to remains in the window when calendar
preferences is re-opened.

Is there a fix for this?
Thanks in advance.
