Can SharePoint Server 2007, InfoPath 2007 & Outlook 2007 co-work with InfoPath 2003 & Ou

If I develop a workflow on server side, will this configuration work?

Server side: SharePoint Server 2007, InfoPath 2007 & Outlook 2007

End-user side: InfoPath 2003 & Outlook 2003

For example,

1. End-user submit request via InfoPath 2003 Form & Outlook 2003 and then the InfoPath 2003 Form can be stored in SharePoint Server 2007.

2. End-user will get an email once the process is done on server side.

Thanks.
