What Microsoft 365 feature restricts communication and information sharing between two departments?

The feature that restricts communication and information sharing between two departments is Information barriers. Information barriers are a compliance feature specifically designed to ensure that sensitive information is not shared inappropriately between groups or departments within an organization. They help organizations comply with regulations and internal policies by preventing users in one group from communicating or sharing certain data with users in another designated group.

This feature is essential for organizations that need to segment access to sensitive information based on roles, responsibilities, or compliance requirements. By implementing information barriers, organizations can ensure that critical data remains secure and interactions are properly controlled.

In contrast, sensitivity label policies are meant for classifying and protecting data based on its sensitivity rather than restricting communication. Customer Lockbox is a feature that grants customers control over access to their data by Microsoft, but it does not restrict inter-departmental communication. Privileged Access Management (PAM) provides a way to manage and monitor access to privileged accounts and resources, but it is not designed to manage the communication boundaries between departments.
