EX13-CA-000005 - Exchange must use Encryption for RPC client access.

Information

This setting controls whether client machines are forced to use secure channels to communicate with the server. If this feature is enabled, clients will only be able to communicate with the server over secure communication channels.

Failure to require secure connections to the client access server increases the potential for unintended eavesdropping or data loss.

Solution

Open the Exchange Management Shell and enter the following command:

Set-RpcClientAccess -Server <ServerName> -EncryptionRequired $true
