Safeguarding Sensitive Data in Microsoft 365 Copilot with Purview DLP (GA Release)

on
The challenge with sensitive data and access to Copilot Microsoft 365 Copilot empowers users with AI-driven assistance across Microsoft 365 apps, but it also raises concerns about accidental oversharing of sensitive information. In response, Microsoft has extended its Purview Data Loss Prevention (DLP) capabilities to Microsoft 365 Copilot, allowing organizations to enforce information protection policies within AI workflows. The DLP for Microsoft 365 Copilot has been in preview for some time, but Microsoft has now announced it is released for GA (General Availability). Among some of the interesting features are new features like alerting and policy simulation. Key details:  Rollout Timeline: As of June 2025, the rollout has begun. It should be completed worldwide by late July 2025. Scope: Initially, DLP for Copilot was available for Copilot Chat scenarios.

Missing Meet URL for users of Lync Hoster Pack v2

on
The company I work for deployed Lync Hoster Pack v2 in the fall of 2013. At first, all things seemed fine, but after a while we received incident tickets regarding users who did not get the meet url published when creating a new meeting.

It has been a long road tring to find the root cause of this issue, especially since we at first saw no difference between the users we created where it worked, and users where it did not work. All users were deployed through the Citrix Cortex service for provisioning.

All users were provisioned correctly with Domainmap, TenentID and ObjectID. And if we moved users from one place to another it started working again.

It all turned out to be a rights issue in Active Directory. The root OU had it's correct settings, but when we deployed several resellers through the Cortex service, these reseller OU's did not inherit the rights from the parent OU. Applying the correct rights to all the sub OU's in the tree fixed the issue for all customers.

Here's a quick script to set the correct rights for hosting on all OU's in a tree:

Import-Module activedirectory
Import-Module lync
$counting = 0
$moreISH = Get-ADOrganizationalUnit -LDAPFilter '(name=*)' -SearchBase `
'ou=reseller,ou=hosting,dc=domain,dc=net'| select DistinguishedName
foreach ($ou in $moreISH){
Grant-CsOuPermission -OU $ou.DistinguishedName -Verbose -ObjectType user
$counting ++
}
Write-Host "Set rights on $counting OU's" -ForegroundColor Green

The commands above must be run a computer where the Active Directory and the Lync module is available.
