De-duplicating contacts based on Firstname-Lastname
I need to deduplicate my Contacts based on First Name and Last Name (i.e. those Contacts which have the same firstname and the same lastname. There does not seem to be any way to do this - my choices seem to be limited to what you see in the screenshot. And yet I have a hard time believing that this is not possible... Does anyone know how to do this? Many thanks in advance
