I lost the address button on received email. How do I get it back

When I receive email and open it, I usually see a grey button to click if I
want to add the sender to my contacts. Yesterday, I had a problem with
computer freeze and outlook had to fix itself. Now the button doesnt show up
on any emails received. Is there something I can do the get the button to
reappear?
