Microsoft Purview Sensitivity Labels: Sensitivity label grouping modernization coming this fall (?)

There is a change coming to Microsoft Purview Information Protection that simplifies sensitivity label architecture. The goal is to make label management easier, more scalable, and less rigid for organizations. The new model will only include standalone labels and sublabels. Parent labels will be replaced by label groups, which act as organizational containers. These groups cannot be applied to content and have no actions or scope, but they retain color and priority for visual organization. Hopefully, this change will make it much easier to move labels around and make other changes in production: for example, converting a standalone label into a sublabel or moving sublabels between groups without breaking dependencies.  From my experience, this update solves one of the biggest challenges in large environments: rigid label hierarchies.

How to locate users without the EXT in line uri and add it to them

Sometimes added users do not get their EXT set in their LineURI as they should, and it can be a frustrating to locate these users and to edit the lineURI to the proper format.

Fortunately, we have powershell for those kind of jobs. The following example will locate any csuser with a lineURI but without the extension set. Then add the extension to the lineURI and save the configuration.
$extSet = Get-CsUser -filter {lineuri -notlike "*ext*" -and lineuri -ne $null}
foreach ($user in $extSet){
$myURI = $user.lineuri
$myURI = $myURI + ";ext=" + $myURI.substring($myURI.length - "4") 
set-csUser -Identity $user.displayname -LineUri $myURI -verbose}

The example above will add the extension of 4. Edit this as fit for your environment.
I will add this example to the PsCommands sections as well
