Ensure external file sharing in Teams is enabled for only approved cloud storage services

Why This Matters

Configuring external file sharing in Microsoft Teams to allow only approved cloud storage services reduces the risk of data leakage through unauthorized third-party platforms. Without this control, users may inadvertently share sensitive company files with external services that lack appropriate security and compliance controls, exposing your organization to potential data breaches and regulatory penalties.
