Bilateral chat policy is a new type of policy for restricting external group chats in Microsoft Teams to maximum of two organizations. This policy will be available for admins to set up and apply to users and groups where external access policies are already set up. After the policy is enabled, automatically enforced compliance controls will prohibit users from creating or adding users from more than two organizations to external group chats.

This message applies to Teams for Windows desktop, Teams for Mac desktop, Teams on the web, and Teams for iOS/Android.
