We have recently purchased some versions of 2010 Office for new laptops, however we are still running the 2007 version of Infopath. We have several forms created that utilize the e-mail button to distribute via Outlook. We are finding that the e-mail button no longer works on these forms when using the 2010 version of Outlook, even though they work in Outlook 2007. Any ideas on why? Is there something we can do to make the e-mail button functional again?
