Hello, My system consists of a FreeBSD box running sendmail. The clients are running Windows Outlook 2003. I would like to be able to share Contacts, Calendar etc but am unable to unless connected to an MS Exchange Server. Is there a way to emulate this connection between Windows Outlook 2003 and Sendmail so that Windows Outlook 2003 thinks it is connected to an MS Exchange Server. There wasn't a problem when using an MS Windows Outlook 98 Thanks, Ivan
