I provide IT for a small company that has employees that are on the road. I
had to disable relaying on our Exchange Server SMTP because of issues with
ISP refusing our mail because of Open Relay. When I did that, now the outside
employees cannot send mail when they are at a hotel.

Is there something I can modify on their Outlook setup or on the Exchange
Server that will allow them to send mail from these (hotel) locations?

Thanks!
