I have what I think is a simple issue but I am getting inconsistent advice from several Sharepoint consultants. I am using Microsoft Sharepoint in Office 365. I have a form in both Infopath and HTML formats. I want to have an anonymous user on a public (non-sharepoint) website to be able to complete the form and attach documents and then have the form's data and documents appear in a Sharepoint list or library. The site from which the form will be completed is SSL secured. I would like for the form to be filled out and submitted without the person having to log in to sharepoint or office 365. Some sharepoint developers have told me that this cannot be done. Others have told me that it can be done but none have been able to demonstrate this to me. I am looking for a developer who has actually accomplished this and can provide me with a demonstration that it works.
