Hi, Can we make info-path forms no longer admin approved in SharePoint 2013/2016?Currently i am using admin approved form template with code-behind.Is there any alternative approach to publish it to SharePoint with out using admin approved form template? Thank You

This is not SharePoint online, right? If your form's code is compatible, you may be able to sandbox it. What does your code do?

It is on-premises.I have few data connections as well.Is it possible to sandbox data connections as well especially email data connections?I have a buttons event handler code which is used to submit data.
