Palm Treo 700w / 700wx

I'm upgrading to a Palm 700w and have an Exchange 2000 server at the office. I would like to be able to sync Calendar, Contacts and E-mail. Since I don't have ActiveSync on my Exchange server I plan to use Wireless Sync to keep the information synchronized. If I understand correctly, I need to have Wireless Sync installed on my workstation and have Outlook open all the time.

Does anyone know if there are issues with using Exchange 2000/Outlook 2000 and Wireless Sync or have any experience using their Treo with them?
