External Sharing in SharePoint and OneDrive is changing: What You Need to Know

In an ongoing effort to create a more secure environment by default, Microsoft is introducing an important security update that will affect how external users access content shared through SharePoint and OneDrive.

As before, the script can be found at the technet gallery (link)
