I'm using Sharepoint 2013 online with Office 365.
Is there any way for an anonymous user to communicate with the site using forms (preferably Infopath)?
There are many, many versions of this question on the web. Several lead to http://claytoncobb.wordpress.com/2011/06/03/infopath-allowing-anonymous-users-to-submit-forms-in-sharepoint-2010/, but this is about Sharepoint 2010, not 2013. Other answers talk about features that are not in Sharepoint online 2013, such as Application Management in Central Administration. There is also a Sandbox solution from CodePlex that gets touted,https://anonymous365.codeplex.com/, but this fails in Sharepoint Online 2013.
The only feature I can find is the Excel Survey in Form Templates. This is at least a start, but what I really want is the ability for an anonymous user (a customer) to submit information into a Custom List using a form; or, second best, in an email (WITHOUT having to have Infopath Filler installed). Seems a pretty basic need, really - letting your customers place orders. This is all do-able for a fully-subscribed user of the intranet site, but I can't afford to buy individual subscriptions for all my customers. Nor do I want them seeing each other's data, or accessing my intranet!
I have spent so long researching this and getting nowhere, and really need to know if it's just a straight 'no, it's impossible', or keep trying.
Thanks
