Announcement: Updated guidance and tooling for governing sandbox solutions in SharePoint Server

Code-based sandbox solutions were deprecated in SharePoint Server 2013 and in SharePoint Online in January of 2014. We began removing code-based sandbox solutions from SharePoint Online in recent months, and as another step in that journey we’re updating our guidance for code-based sandbox solutions in SharePoint Server on premises. In addition, we’re releasing a new capability to help you manage code-based sandbox solutions in running SharePoint 2010, 2013 and 2016. Please see this blog post for details.
