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. This change applies to all organizations that have already enabled or will enable SharePoint and OneDrive integration with Microsoft Entra B2B (Most organizations I have looked into so far).

Searching for that LineURI - Again

This is a script I have not used for a while, and when I needed it recently I discovered it would not run properly on a Lync 2013 server. I decided to rebuild the script to adapt to Powershell v3 and Lync 2013.

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.
