Hello Mo, thank you for you responds. But I know the principle of working with e-mail connection on InfoPath. But then you will need InfoPath filler to read or change the form. My objective is to make the forms available for everyone, also those users which do not have InfoPath. Therefore the form must be a webbrowser based form, installed on a SharePoint site. This principle (sendig e-mail with InfoPath form to the submitter), after been submitted to SharePoint site, would work when I make the form full trusted and published it on a on premises SharePoint server. But this is the problem, I don't have an on premises SharePoint server but an online SharePoint server (plan E3). So, your solution will not work for me. With regards, Otto
