About this tag
Entra B2B governance refers to the policies and controls that manage external guest access in Microsoft Entra ID, particularly in Microsoft Teams. A recent change enables email-to-chat functionality, automatically provisioning external recipients as guests in the sender's tenant. This feature is enabled by default and governed by Entra B2B guest controls, requiring administrators to review and adjust policies to maintain compliance and security. IT teams must account for this update, which rolls out in stages from early November 2025, and can be disabled via Teams messaging policy. Effective Entra B2B governance ensures that guest access aligns with organizational security and compliance requirements.
