Microsoft Teams is adding Brand Impersonation Protection to warn users about suspicious first-time external callers, reducing social-engineering risk in call flows. The feature will roll out to the targeted release ring in mid-February and be enabled by default, expanding call-time protection without admin setup. Microsoft says the warnings are meant to flag calls that appear to impersonate trusted organizations before users answer.
