Error message: The custom form cannot be opened

Error message: The custom form cannot be opened. Outlook will use an Outlook form instead. The form required to view this message cannot be displayed. Contact your administrator.

What does this message mean? Is there something I can do myself to correct it? It comes up everytime I get a calendar item for a meeting sent to my inbox.

Thank you.
