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.

This client has been in preview for Microsoft 365 subscribers for some time, but it is now also rolling out to private user accounts as well. 

You can read about the new client, and how to get started in this blog post.
