Can you provide additional information as to what the Outlook CDO patch will affect if it is not applied?

Q: Can you provide additional information as to what the Outlook CDO patch will affect if it is not applied, I think that there is confusion as to whether this is needed to fix calendaring issues within Outlook 2003.
A: If you do not apply the CDO patch, appointments and meetings on calendars accessed via OWA or CDO dependant handhelds, such as Blackberry or Goodlink, may not show the correct time.
