Let's say you have a Blog site hosted in Office 365 and you write a blogpost. Users in SharePoint can comment and leave a likes, Use Hashtags and mentions. If we make the blog public so everyone can see:
Is there a OOB(Out of the Box) way to give visitors on the blog the possibility to give feedback without having a Office 365 account?
I assume I can create the functionality in an App-part that we can replace the normal "comment field" with, containing some required fields like Name, e-mail and comment.
