When you create or open a contact item that is based on a custom form, you may receive the following error message:
If you click OK, the contact item opens.
The property does not exist. The field you want to modify is not valid for this type of item.
The custom Contact form was designed by using Microsoft Outlook 2000. In Design mode, the General page of the form was modified (a control was added, moved, removed, or resized), and then the form was published or saved as an Outlook template (.oft) file. When you access or create items based on this form by using Outlook 98, you may receive the error message that is mentioned in the "Symptoms" section.
This error message is caused by the retention of the Contacts command button control and the associated text box control on the General page of the form. These controls are responsible for contact linking features in Outlook 2000 that are not available in Outlook 98. When you design a custom form and modify the General page of the form, the page is added to the ModifiedFormPages collection of the item which results in incompatible controls for Outlook 98.
Use one of the following methods to prevent this problem:
The Contact form in Outlook 2000 is different than the Outlook 98 Contact form because Outlook 2000 has contact linking Contacts controls (a command button and a text box). For backward compatibility, the default version of the Outlook 2000 Contacts form (Ipm.contact) does not display the Contacts controls in Outlook 98.
