Remarks

You can define custom properties for Outlook items by calling either the UserProperties.Add method for an Outlook item or the UserDefinedProperties.Add method for a folder.

You cannot add custom properties to Office document items such as Word, Excel, or PowerPoint files. You will receive an error when you try to programmatically add a user-defined field to a DocumentItem object.
