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).

What is a Charter certificate


I have been a mcp since 1998, and never been aware of the charter "program". So I was a bit surprised when I discovered the line on the two newly downloaded certificates.

Charter Members are recognized by receiving the Charter version of the certificate acknowledging their early adoption of the certification.


In all my years as a mcp, mcse ++, I've always been told they're worth "nothing" and that anyone can just braindump themselves to a title. Well, hat off to Microsoft for recognizing those who certify early. Now I can say I have proof that I did not braindump my way to the Lync. There is no way the braindumpers get around to create good dumps within the timelimit given.

These to certifications now really mean something for me and my employer. And now that I am aware of the program, I'll strive to take the next certification as a charter member as well.
