Can you use information barriers with Microsoft Exchange?

Information barriers are a feature designed to prevent certain groups of users from communicating with each other in environments such as Microsoft Teams and SharePoint. However, when it comes to Microsoft Exchange, information barriers cannot be implemented.

Microsoft Exchange is primarily focused on email communications, and the use of information barriers is not supported within its architecture. This means that even if you have set up information barriers in other Microsoft 365 services, these barriers won’t extend to emails sent through Exchange. Thus, organizations looking to enforce communication restrictions among users through Exchange are unable to leverage information barriers in the same way.

Understanding how information barriers are applicable only in specific contexts within Microsoft 365 services can help clarify their limitations in Exchange. This reinforces the idea that while Microsoft provides various compliance tools, the scope and functionality can differ significantly depending on the application and the service being utilized.
