How could I force Outlook to look for names in my contacts ?

Hi,

I don't like the Auto Complete function in the New email window as it's
quite messy. Instead, I'd like Outlook to start looking in my contacts for
all the names starting with the letter R, for instance, when I type an R in
the "To" line and then refine the search as I type the second letter, third,
etc.

Is that possible ?

Thanks.
