I am needing to create a customized version of the appointment form for a
calendar in Outlook, but when I select the Appointment form from the Design
a form menu, it opens but I can't edit the form. I can create customized
versions of the other forms (the contact and message form for example), but
I can't edit the appointment form. Also, upon further inspection, I can't
edit the Journal Entry or Task forms, either.

Is there a reason for this? Can it be overridden? Is there another approach
I can take with this?

I am using Outlook 2003 on Windows XP Professional.

Any help would be greatly appreciated!
