Have a look at my GitHub SharePointOnline-ScriptSamples, where you can find this SharePoint script and 280 others!

You can find all my repositories at PowershellScripts @ GitHub


Short Powershell script sets the external sharing setting in SharePoint Online and controls how users share content with people outside the organization.

It sets sharing outside the organization using CSOM and requires SharePoint Online SDK.

The script is part of and more described in a TechNet Wiki SharePoint Online Sharing settings with CSOM article.
