What is a key feature of conversations that have been captured for retention?

A key feature of conversations that have been captured for retention is that they will be marked with a classification authority block. This marking is essential because it indicates the origin of the material's classification and provides the necessary context for how the information should be handled, accessed, and disseminated. The classification authority block serves as a vital guide for ensuring compliance with regulatory requirements and organizational policies regarding classified information.

In the context of retention, having this classification marking is crucial for maintaining security protocols and informing personnel of the information's sensitivity level. Without such markings, there could be confusion about how to treat or share the information, potentially leading to unauthorized disclosure of sensitive content.
