Financial institutions consider chat messages as a form of data exfiltration, so it’s imperative for IT admins to gain flexibility and control over chat access for anonymous or unauthenticated users. The latter may be expected to join Teams meetings, but they should be restricted from seeing and accessing any type of electronic communication on chat. This feature provides additional security by only disabling chat write access for non-federated users and unauthenticated users who join Teams meetings through a link, so it must be used in conjunction with disabled meeting chat policy applied to financial advisors to remain compliant. This message is associated with Microsoft 365 Roadmap ID 91142.
IT admins can now disable chat write access at the policy level for non-federated users and unauthenticated users who join Teams meetings through a link that must be used in conjunction with disabled meeting chat policy to provide additional security against data exfiltration.
