Ensure additional storage providers are restricted in Outlook on the web

Why This Matters

Allowing unauthorized storage providers in Outlook on the web increases the risk of data exfiltration, as users could attach files from unapproved services that bypass your organization’s security controls. Restricting these providers helps prevent sensitive data from being shared through untrusted third-party storage platforms, reducing your attack surface.
