This policy setting allows you to specify whether replies will be automatically signed.
If you enable this policy setting, the option to respond automatically to a signed message with a signed response will be overridden, and an unsigned response will be the default reply to a signed message.
If you disable or do not configure this policy setting, a signed response will be the default reply to a signed message.
