I currently have a Treo300 and thinking about ordering a T-Mobile Treo600 before the upgrade discount period ends on Tuesday. I use the Treo300 while I'm in the US and a T-Mobile phone when I travel overseas as they seem to have very good coverage and roaming rates.

Of course, while in the US I use Sprint's Business Connection Personal Edition to link to my Outlook e-mail and Exchange Server for just $5/month. Will the T-Mo Treo600 come with software to allow me to access my Outlook e-mails? Do they have an option to do this like Sprint does? If not, any recomendations on how to economically do so for a single user?

Thank you in advance for your replies.
