Not sure of the right terms to use for this, but when I type a recipient's name in Outlook, it searches a directory and lists the potential matches. Both the accounts I use on Outlook are Exchange accounts. Decided to try Apple Mail to see if I can by with a simpler interface. So far, I am liking Mail, except that it doesn't do the directory search as Outlook does. I am sure Apple did not miss this out, so I wonder if I am not doing it right?
