Ensure 'External send connector authentication: IgnoreStartTLS' is set to 'False'

HochStufe 1Automatisiertexchange

Beschreibung

This policy setting specifies whether to ignore the StartTLS option offered by a remote sending server. StartTLS is a protocol command used to inform the email server that the email client wants to upgrade from an insecure connection to a secure one using TLS or SSL. Prints the number of Send connectors where IgnoreSTARTTLS is True (expected 0). 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.
