Informaiton barriers is not working as documented

Please i need your help on this issue.

At the end of October we enabled Information Barriers in our organization and everything was working fine.

However, we have detected that legitimate users are blocked from accessing some Teams meetings, even sometimes they are blocked from meetings created by themselves.

I have tried to disable and re-enable IBs and swapping members from segments, but nothing seems to work.

I used this tutorial to implement IBs

Currently we only have implemented them on Teams, and we are planning to extend them to SharePoint.

For your information, our deployment is very simple: we have two segments where users are splitted depending on their department attribute.

The problem is that users from the same segment sometimes cannot join teams' meetings. This is quite random because sometimes it works, sometimes it does not work.

Once a user reported that Microsoft blocked him when he was accessing the meeting but a minute later he was able to access the meeting.

The Problem started on Tue, Nov 1, 2022.

    Hi @Iniobong Nkanga

    Try navigating the troubleshooting guide:

    Issues with communications and information barriers

    If the guide is not exposing the problem, it does state "If you are still having issues with your information barrier policy, contact support." You will want to contact support via the Admin Center:
