Which statement describes the relationship between EAC and Microsoft 365?

• A. EAC provides an experience more in line with the Microsoft 365 suite
• B. EAC is a standalone product with no Microsoft 365 integration
• C. EAC only supports on-premises Exchange with no cloud integration
• D. EAC is a mobile app only

Answer: (C)

Exchange Admin Center is the management interface for Exchange Server. In the Microsoft 365 world, cloud-based Exchange Online is managed from its own cloud admin experience, while EAC serves as the on‑premises management console. In hybrid setups you can configure coexistence and see some cloud-related state through the on‑premEAC, but the day-to-day cloud mailbox management sits in the cloud’s own admin center. Therefore the statement that EAC is tied to on‑premises Exchange with no cloud integration best captures the general relationship: EAC is primarily an on‑prem tool, and cloud management is handled separately in Microsoft 365. The other options misstate this mix—EAC isn’t a Microsoft 365-aligned experience, isn’t simply a standalone tool with zero integration (hybrid scenarios exist), and it isn’t a mobile-only app.
