We have migrated a 7.5 Service customer to 8.4. In 7.5 they intensively worked with the address book (the one from the knowledge base). But If they want to add a recipient in 8.4 you get both all records from the address book as the person table.
But the main problem, is that you can only search in the current recipient field, but you cannot browse the address book anymore.
Is there any feature to browse the address book when adding a recipient in 8.x?
