T68i & Sony Clie NZ90

Hi,

Does anyone have any experience of setting up the following combination ?

Sony Clie NZ90 running Palm OS 5, using T68i connected by Bluetooth, to
configure a VPN over the Internet to synchronise Outlook with an Exchange
2000 server.

Is this possible and if so, what configuration and additional
software/drivers would be required on the Sony Clie NZ90 to make this work ?

The users network is O2 in the UK.

Thanks
