EX19-MB-000061 Exchange local machine policy must require signed scripts.

Information

Scripts often provide a way for attackers to infiltrate a system, especially scripts downloaded from untrusted locations. By setting machine policy to prevent unauthorized script executions, unanticipated system impacts can be avoided. Failure to allow only signed remote scripts reduces the attack vector vulnerabilities from unsigned remote scripts.

Solution

Open the Exchange Management Shell and enter the following command:

Set-ExecutionPolicy RemoteSigned
