Ensure 'Require client MAPI encryption' is set to 'True'

높음레벨 1자동exchange

설명

This policy setting specifies whether encryption is required for Remote Procedure call (RPC) client connections. Note: This recommendation only applies if RPC over HTTP is enabled in the organization. In Exchange 2019 MAPI over HTTP is enabled by default. Prints the number of RPC client access configurations where EncryptionRequired is not 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.
