In Dynamics CRM, the "Regarding" field is not displayed in Outlook 2010, if primary field is empty. (Primary field is a field whose value is displayed in lookups.)
Say we have a lead where First Name and Last Name are empty. In IE it will display only icon, but it's still clickable.

In Outlook there's no icon, so it is not clickable.

Is there a way to display icons of "Regarding" entity, or make it clickable in any other than modifying data?
