GENERAL COMMENTS

This sample shows how you can control the external sharing settings for a site collection in Office 365 MT. This “External sharing” capability is not available for on-premises and Office 365 dedicated deployments. In order to use external sharing it first needs to be enabled at tenant level: the code will check this like shown below:

SharingCapabilities _tenantSharing = _tenantAdmin.SharingCapability;

if(_tenantSharing == SharingCapabilities.Disabled)
{
  Console.WriteLine("Sharing is currently disabled in your tenant");
}

If external sharing is enabled at tenant level then you can control the external sharing setting via below code:

SiteProperties _siteprops = _tenantAdmin.GetSitePropertiesByUrl(siteCollectionURl, true);

_siteprops.SharingCapability = shareSettings;
_siteprops.Update();
adminCC.ExecuteQuery();

Where shareSettings is an enum:

public enum SharingCapabilities
{
  Disabled = 0,
  ExternalUserSharingOnly = 1,
  ExternalUserAndGuestSharing = 2,
}
