Exchange Mailbox has Junk E-mail and Correo Nao Solicitado

An Exchange 2003/Outlook 2003 user went to Portugal and came back with an extra folder in his Outlook. Now, junk mail is no longer going to the Junk E-mail folder, but instead being redirected to the magically created Correo Nao Solicitado folder. How can I get rid of the Correo Nao Solicitado folder?

Thanks,
Jamie
