We have a provider that is using SharePoint Foundation 2013, and our users are having difficulty with CoAuthoring documents. In Office 365, the users can see each other in the document, and they are able to edit the same paragraph. Also, it autosaves without the users having to do anything. In the solution that our provider has, our users cannot edit docs easily, and they have to "save". Is this a limitation to Server Foundation 2013? Or any On Prem server? Would we basically have to have Office 365 in order to do seamless coauthoring?
