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. Highlights of how the change affects organizations who have enabled B2B: All external sharing will require guest registration. External users must be added as guests in your Microsoft Entra directory. Access will be managed through Microsoft Entra B2B Invitation Manager. T...

This fall has been really busy, and it isn't over yet!

As I am writing this post, we are less than one week away from the first Norwegian Lync Day, where I will hold a presentation on Lync backup and restore. Ståle Hansen and Knowledge Factory has done a great job to gather highly qualified MVP's and speakers for a day packed with great sessions around our favorite topic: Lync! For more information and/or signup, go to: http://lyncday.no/

When Lyncday is over, it will be just two more weeks until most of us head for Barcelona, and TechedEU. Here I'll be holding a similar presentation around the same topic (Backup and restore / http://teeu2014.eventpoint.com/speaker/details/c27e77c2-7d22-e411-9bad-00155d5066d7).

As a preparation for these to presentations I have gone over my backup script for Lync 2013, and I am planning a major release change with a few new options and a couple of bugfixes. If you do have a bug you want to report in the existing version or have a suggestion for a new feature. Please drop me a line. It's not to late to get your request included.

Here's a sneak peak on some upcoming changes:

  • FEATURE REQUEST: Remove "temp" files after zip creation, to save space (note: Script will still clean files in target directory, older than 5 years)
  • FEATURE REQUEST: Identify RGS servers on 2010 pools, and remove error messages related
  • FEATURE REQUEST: Identify User servers on 2010 pools, and remove error messages related
  • New feature: Added progress bar, to indicate progress within the script
  • Bugfix/New feature: Multiple pools could lead to "file already exist", Script should store pool files in designated pool folders
  • Bugfix: If SQL backupshare already exists, it is now detected and should no longer be causing errors
I won't be able to publish for Lyncday, but it will be out in time for TechedEU
