How do I make the standard contact form the default?

[a_ryan1972]

Hi, I'm using Outlook 2007. When I try to open a contact I get a message
saying "The custom form could not be opened. Outlook will use an Outlook
form instead. The form required to view this message cannot be displayed.
Contact your administrator."

It then opens in the standard form. I do not want to use a custom form and
this happens every time I try to open a contact. How can I set it so that I
can use the standard as default?

Thank you.
