Store emails in specified network folder

One of my clients wants all of their users Sent emails to be automatically copied to a folder on their server, as well as their e-mail sent items folder in outlook.

They are using SBS 2008, Exchange 2007, and Outlook 2007.

Is this possible? I am somewhat familiar with exchange, but not so much as to know if this is possible. My searching for this answer has led to seeing that it can be copied to a public folder in exchange, but they want it to go directly to a data folder on their server. They would want a copy of this sent e-mail (*.eml) format to be auto ccd to this Network folder.

Any help is appreciated!
