Question : Add Spanish dictionary in to Office 2007 english

Is there a way I can get the Spanish language to be recognized in my spell check dictionary?

I'm sending e-mails in Outlook 2007 but occasionally add words in Spanish depending on which customers I am e-mailing.

Our IT staff has the Spanish 2007 discs and the MUI but we're not sure which to install, or if there's a download we can get for free to achieve this.
