What is the term for communication that occurs between different offices or departments within the same organization?

The term that best describes communication occurring between different offices or departments within the same organization is "interdepartmental." Interdepartmental communication refers specifically to the interactions and exchanges of information that take place between distinct departments, allowing for collaboration and coordination of efforts to achieve common organizational goals.

In many organizations, effective interdepartmental communication is essential for ensuring that all parts of the organization work harmoniously together. It helps to eliminate silos, enhance understanding of each department's contributions, and improve overall efficiency.

While "internal" also refers to communication within the organization, it is broader and can include communication among individuals at the same department, teams, or even within the same office. "Corporate" typically refers to larger organizational strategies or structures and does not specifically denote communication among departments. Similarly, "interoffice" focuses more on communication between offices rather than specifically on departmental exchanges. Therefore, interdepartmental is the most precise term for this type of communication.
