How Microsoft Purview DLP currently can help you protect confidential data in Copilot.

on
Organizations today face a difficult balancing act. Business leaders are eager to adopt tools like Microsoft Copilot to unlock productivity and innovation. Meanwhile, IT and security teams are concerned about safeguarding sensitive information, especially as AI-driven features process vast amounts of organizational data. This tension is real: enabling advanced capabilities without compromising compliance or data protection is a challenge every modern enterprise must solve.

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
