Exchagne 5.5

I have installed exchange 5.5 in the Head Office and downloading emails from ISP and then distributing to other users in my company. Three employees are located remotely and need to access and download their emmails to their local machines.

I would appreicate if any one could help me to achive this goal. I have limited knowledge of exchnager server and need urgent support.

I thought about OWA,I have never worked with it but beleive it does not allow users to download the email but view only. Second, OWA need high speed connection, meanwhile I have dialup connection in the HO as well as remote locations.

Please help
