The GUI way, still in preview

Microsoft is all the time heavily adding new options for their products and some of them goes with out us even noticing.

There is one for Information Barriers Segments, which is again a nice addition to comply with easiness of use.

It can be found under Compliance -> Information Barriers -> Segment

Here you can add your segments (with the same attributes that was shown before in this post.

Then you will create the segment and you can use this group inside your segment.

You will create two segments.

Then to policies

Policies is also in preview.

Create policy and select the first segment.

In the next screen you will choose will you block or allow the other segment.

And set status On or Off

Now you have the Segments and the corresponding policy.

And then to Policy application.

Run "Apply All Policies"

And you will get and error saying, that the policy should be symmetric.

Go to create a new policy.

Then again to Policy application. Now you will notice that the applying is starting.

And eventually it will change to Apply In progress.

And the done, so it took about 20 minutes to complete.

When you try to send Teams message to the user in the other segment, this will happen.

But with email it still wont work. Like it was before.
