Ensure 'Require encryption on device' is set to 'True'

高レベル 1自動exchange

説明

This policy setting specifies whether encryption is required on the mobile device before it is allowed to connect to the Exchange environment. RequireDeviceEncryption must be True. Prints the number of mobile device mailbox policies that do not comply (expected 0). Run on a Mailbox server; every mobile device mailbox policy is checked. 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.
