This links the file host to the organization. A host is specific to an organization and an organization can only have one host.
You can view files from their original location if a relationship does not exist between a company and a user or between a company and a host. No defined relationships are equal to having a blank value for the LocalFileServerfield option. If you are configuring integration with SPO/E, you must add the SPFOrganizationFileServerHost relationship.
