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

on
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. The new dynamic model gives admins the agility they need to adapt quickly as compliance and business needs evolve. For admins, migration will be quic...

Lync client may connect to a non federated partner, even if you though it should not.

Here is an "interesting" observation I did a couple of days ago. The customer has chosen not to allow DNS discovery of federated partners, but will allow federation with selected partners on the allow list. After a while with this configuration, the customer called me and told me they had mixed experiences with the solution. There were times when meetings with a partner (NOT on the allow list) actually would work, even if they expected the meeting to fail.

They asked me to verify the settings, and to investigate why some users reported they could connect to a meeting others couldn't.

This is what I saw on a client who failed to connect:




5 messages. And the interesting one would be the 504 message: "Can not route".



And then the client stops trying, as I would expect it to.

But here is an interesting twist. Log on with the same client from a remote connection (through edge), and then let's see what happens.



The client does not honor the 504 message "Can not route". It continues and connects to the meeting, unexpectedly. How can that be?

The interesting part is what happens after the 504 message. First the client acknowledges the rejection, but then it does something it didn't do on the inside. There is a new invite, trying to connect anonymously:



And this connection is allowed. Quite confusing for the end user, actually. But now they know.


It is important to note the user was allowed for federation in this scenario, but the domain in question was not in the allow list and DNS discovery was not allowed. Also, the organizer on the other side was allowing anonymous invites.
