Outlook and Infopath not communicating?

We are running Vista Business, Office 2007 and Infopath 2007.

One user does not have the option in Infopath to “Send to Mail Recipient” in the file menu. This same user does not have the option in Outlook to “Choose Infopath Form” in the new drop down menu.

I have tried several fixes and checked settings on .xml, default programs, even repaired infopath. In Outlook advanced options, “Enable Infopath forms” is checked.

Does anyone have any other ideas to help me? Should I completely uninstall and reinstall Infopath? What other reasons would the two programs not be talking to each other?
