Palm Treo 700w / 700wx

My significant other is debating getting a treo 700x (p or w) on Verizon but she needs to be able to use her company email account (exchange 2003) for her own email, calendar, contacts etc as well as her bosses calendar also on exchange as she's an assistant to the CEO and needs access to his calendar as well. Is this possible on the 700x (p or w) and if so, how?

Thanks!
