Ensure 'Enable automatic forwards to remote domains' is set to 'False'

높음레벨 1자동exchange

설명

This policy setting is used to determine if the server can send automatic forwards to remote domains. Prints the number of remote domains where AutoForwardEnabled is not False (expected 0). Automatic forwarding to external domains is a common exfiltration path. Every remote domain (including Default) is checked. Run on a Mailbox server (organization-wide objects are read from AD). Run from an Exchange Management Shell or after `Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn`; the audit loads the snap-in itself when Get-ExchangeServer is missing and fails if it cannot.
