Ensure no accounts are configured to bypass mailbox audit logging

높음레벨 1자동exchange

설명

Accounts with AuditBypassEnabled can access mailboxes without generating audit records. Prints the number of bypass associations (expected 0). 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.
