Custom properties are new properties that you add to an existing item type. For example, you could add Referral Source and Age properties to the external user profile.

Depending on how your item mappings are configured, custom properties may automatically display in the Details pane when an item of that type is selected. For information on how item types specify properties, see the Specifying Properties to Display section. Locate the parent item view mapping and item view mapping and adjust their settings accordingly.

If necessary, update property groups so the new properties are visible to the Multi Edit tab. See Creating and Defining Multi Edit Property Groups.
