Overriding default forms in outlook 2000.

I have replaced the default outlook mail forms(IPM.NOTE) , by my created forms, with some extra features.The compose form is getting published normally replacing the default but the read form is not published and cannot replace the default read form used to read emails in outlook.What could be the possible reasons for this and what are the conditions under which we cannot override the default form?
