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.

An "important" lesson from day one at Lync 2013 Ignite

on
Lync 2013 comes with new features and new functionality. To support all of these new functions, there has been introduced a big set of new PowerShell cmdlets.
This didn't come as a surprise to me, as I have been playing around with the preview for a bit, and I have been reading Tom Arbuthnot's excellent post on the subject.
One of these "important" new cmdlets is the "Invoke-CsManagementServerFailover" command. Why?
Well, If you are anything like me, you type as little as possible, and you use the TAB as much as possible, you might to look out for this one. My "default" is to type "invoke-csma" + TAB. to get to the Invoke-"CsManagementStoreReplication" and then hit enter.

Unless I now hit enter twice, i will start the process of failing over the CMS.

I have no idea of how many times I'll fail over the CMS before I actually learn to hit tab twice, but I know I'll get there in the end.

So what was the important lesson here? It's not what you have to learn, but what you have to unlearn :)

For future reference, here's a list of all the cmdlets for Lync 2013
