InfoPath Dev

Is InfoPath 2007 compatible with email forms working with Outlook 2010? When I publish and select "To a list of e-mail recipients", I get the message "To use this feature, Microsoft Office Outlook 2007 must be set as the default e-mail program."

To the best of my knowledge, you have to have the same versions of Outlook and IP installed - I know that if you have IP 2010 and Outlook 2007 we have seen issues where the email sent would be blank, and I remember not being able to use IP 2003 email submit connections with Outlook 2007.
