Email addresses of employees do not auto populate

Since AE is connected to Outlook, and employees' emails are in the system in User Profiles,  why can't the email addresses of employees auto populate the "To:" field, like it used to in JD?  When I am sending an email to a client, and need to CC several people in the firm, having to type each of their email addresses in full, is a lot of extra clicks.  I'd like to be able to type in the first few letters of the email address, and then have a pop up of one or two to choose from.  It'd be great to have ANY address already in my Outlook contact list auto populate the same way, but employees seems like a no brainer and a great place to start.
