What are organization news sites?


Organization news sites, also called authoritative sources, are "official" sites for organization news. When these sites are specified as organization news sources, posts from these sites are interleaved throughout all news posts displayed for users on SharePoint home in Office 365, or via the news tab in SharePoint mobile. They are distinguished by a color block on the title as a visual cue. Admins can manage news sources using simple PowerShell commands.
