Assume that you manually move email messages to the Junk E-Mail folder from other folders in a Microsoft Exchange Server 2010 environment. Additionally, you have applied a retention policy to the Junk E-mail folder. In this situation, the Messaging Records Management (MRM) retention policy for the Junk E-Mail folder is not applied to the email messages.
Note By default, email messages that trigger the spam confidence level (SCL) or the phishing confidence level (PCL) are delivered to the Junk E-Mail folder, and then the retention policy is applied to the email messages.
