External Sharing in SharePoint and OneDrive is changing: What You Need to Know

on
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). External users trying to use old links will see an error message saying the organization has updated its guest access settings. To regain access, the content must be reshared.

Skype for Business MVP Award

on
I know it's April Fools Day, but as the @MVPAward reminded us on Twitter today: This is no April Fools: .

About 4:30PM my time, my phone buzzed as I received an e-mail. I'm on vacation, and wasn't really in an e-mail reading mode. But as I glanced at the phone, my heart skipped a beat when I read the heading: "Congratulations 2015 Microsoft MVP!".

I immediately put my vacation "on hold", and powered up my laptop (never far away though, even on a vacation) to read the following email.


This is my first MVP award, and I am utterly humbled, proud, honored and flattered to be recognized by Microsoft and other professional peers like this. It is a good feeling (and indeed a very good day) to be recognized for the hard work and effort put into my work and hobby, and I must send a warm thank you to those who nominated me and supported me for this nomination.

It has been a busy year for me, but I just realized it's about to get even crazier now. I am really looking forward to work with the best of the best, and help spreading my knowledge about Skype for Business in the next months (and years?) to come.

There are posts to write, Meetups and usergroups to manage, conferences to attend as both a speaker and an attendee. And who knows what other opportunities may lay around the next corner. And all of this in addition to my regular work.
