Adding my Contacts to the available addresses in Outlook with Exchange

At my work, Exchange is in use. Mostly that's been great. However, the default setup has not permitted me to be using my own Contacts (and distribution lists) when composing email. This has bugged me no end.

There is a solution however! After digging through the help system, I found My contacts don't appear in the Address Book. Indeed, the check box is not available, so clicking on the How link reveals what to do. Basically, you have to "Add a new directory or address book" (in the Tools > Email Accounts popup). And then after restarting, my Contacts are at long last available when composing email.
