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. Starting July 1, 2025, any links shared with external users before your organization enabled Microsoft Entra B2B integration will no longer work.

Searching for that LineURI - Again

As an update, the script has been signed to be run on any system, and a more appropriate snippet with explanation has been added. And again, this has been added to the Technet Gallery. http://gallery.technet.microsoft.com/Search-for-that-LineURI-814ac281

The script has not been tested on large deployments, so feedback and bug reports are really appreciated.
