Avoid conflicts of interest within your organization by limiting which individuals can communicate and collaborate with each other in Microsoft Teams. https://docs.microsoft.com/en-us/microsoftteams/information-barriers-in-teams, now in Preview, helps limit the flow of information by controlling communication between the holders of information and colleagues representing different interests, for example, in Firstline Worker scenarios.

 

As an Administrator, you can create these policies using the Security & Compliance Center PowerShell cmdlets.

 

Figure 1: Create Information Barriers Policies via PowerShell.

 

Once a policy is in effect, it will apply to Teams events and users will not be able to complete the following actions if they violate any part of the information barrier policy:

 

Action

User Experience if policy is violated

Adding Members to a team 

The user will not show up in search

Start a new private chat 

The chat is not created, and an error message appears

invited a user to join a meeting 

The user will not join the meeting and an error message appears

Screen sharing is initiated 

The screen share won’t be allowed, and an error message appears

Placing a phone call (VOIP)

The voice call is blocked

 

Figure 2: Meet Ethical Wall requirements with Information Barriers in Teams.

 

When a new information barrier is created, the evaluation service searches across Teams to find any pre-existing communications that may violates the policy:

  • Existing 1:1 chats will become read-only
  • Users will be removed from group chats
  • Team membership will be updated accordingly

The ability to create Information Barriers policies during preview is open to all customers. When we announce General Availability of this capability, only customers with the appropriate licenses will be able to continue using this functionality.

    When I saw this I honestly thought maybe it was an April fools joke that I was just now seeing or maybe that an account was hacked.  I've never seen a modern organization that was trying to limit communication, collaboration or information sharing. Seems like most organizations are trying to find ways to tear barriers down, not build new ones. 

     

    I'm sure there's a valid use for this, I guess I just haven't personally experienced it. I've always operated under the assumption if your organization can't effectively share information both horizontally and vertically, from the front line worker to all the way to the CEO, you'll probably die as soon as a competitor comes in that does.

    Will both parties need an A5 license? Eg if you wish to block a First Line Worker from being able to chat with the CEO will both the First Line Worker and the CEO need A5? Or can we just license the CEO?

  • This is great stuff indeed! You mention “only customers with the appropriate licenses will be able to continue using this functionality [when GA]”, what licenses will that be exactly?

  • Great stuff. This will really unblock some scenarios
