These are guidelines that need to be set up by a Microsoft Teams Administrator in order to regulate communications and collaborations between different groups within an organization. In the context of the MS-700 exam – Managing Microsoft Teams – a thorough understanding of how to plan and enforce Information Barrier policies is vital.
Information Barrier Policies: The Basics
An Information Barrier (IB) policy is used to prevent or allow communications among designated user segments. User segments can be defined based on attributes such as department, job title, or location. For instance, a company may want to restrict conversations between departments handling sensitive client material, or between higher management and lower-level employees.
Information Barriers are applicable in scenarios such as:
- One-on-One chats
- Group chats
- Team channels
- Sharing files in chats
- Sharing files in channels
Information Barrier policies can be used to:
- Allow communications and collaborations (Permissive policies)
- Block communications and collaborations (Restrictive policies)
Take note that Teams honors the most restrictive policy. If there’s a conflict between two policies, Teams will enact the policy that restricts communication.
Planning Information Barrier Policies
When planning the implementation of Information Barrier policies, here are a few key steps to consider:
- Identify user segments: Define groups or segments based on attributes such as location, department, or job title.
- Define policies: Identify the types of communications that should be regulated amongst these segments and create clear guidelines on what is permitted or restricted.
- Plan for policy conflicts: Teams honors the most restrictive policy. Therefore, it’s important to plan for potential policy overlaps to avoid unintended communication blocks.
- Communicate policies to your team: Make sure all team members are aware of the policies and understand what they can and cannot do.
Applying Information Barrier Policies
Only global admins and Teams service administrators who are familiar with PowerShell can create IB policies. Here’s the step-by-step process:
- Activate Information Barrier policies: Using PowerShell, select ‘Turn on Information Barriers’.
- Define segments: Define user attributes to segment users. For instance, to segment users based on departments:
$Segment1 = New-InformationSegment -SegmentName "HR Department" -UserAttribute @{Department ="HR"} - Apply Information Barrier policies: Apply the appropriate IB policy, either to allow or restrict communication. To allow communication between segments:
New-InformationBarrierPolicy -Name "Allow HR-IT communication" -AssignedSegment "HR Department" -SegmentsAllowedToCommunicateWith "IT Department"
To block communication:
New-InformationBarrierPolicy -Name "Block HR-Finance communication" -AssignedSegment "HR Department" -SegmentsBlockedFromCommunicatingWith "Finance Department" - Verify and resolve policy conflicts: Use the ‘Check InformationBarrierPolicy’ cmdlet to find and resolve conflicts:
Check-InformationBarrierPolicy -Identity "Block HR-Finance communication"
Information Barrier policies help maintain compliance and security in Microsoft Teams. As a prospective Teams Administrator preparing for the MS-700 exam, honing your ability to plan and implement these policies is crucial. Make sure to refer to Microsoft documentation and practice in a real or simulated environment to master these skills.

Why would an organization want to create information barrier policies?
Information barrier policies are created by organizations to restrict communication and collaboration between certain groups to avoid conflicts of interest, insider trading, or other regulatory risks.
What is the first step to implement information barrier policies in Microsoft Teams?
The first step to implement information barrier policies in Microsoft Teams is to define segments in the Security & Compliance center.
How can an administrator create information barrier policies?
An administrator can create information barrier policies from the Microsoft 365 compliance center by visiting the Information barriers page and following the suggested steps to define policies.

No. Information barrier policies only control chat, calling, and meetings. Other features like file sharing are not controlled by information barrier policies.
How many segments can be created when setting up information barrier policies?
According to Microsoft’s documentation, up to 100 segments can be created for information barrier policies.
How can you validate that an information barrier policy is working as expected?
You can validate an information barrier policy by running a test user communication in which one user from each segment tries to start a chat or establish communication.
How can you edit an existing information barrier policy?
You can edit an existing information barrier policy in the Microsoft 365 compliance center. Go to the ‘Information barriers’ page, and select the policy you want to adjust.
