In the context of Exchange Server, what does Coexistence refer to?

• A. Running multiple Exchange servers in isolation
• B. Running on-premises Exchange and cloud-based Exchange Online in a unified manner
• C. Using different email protocols in an organization
• D. Using a single server for both hosting and database

Answer: (B)

Coexistence in the context of Exchange Server refers to the ability to run on-premises Exchange environments alongside cloud-based services such as Exchange Online in a seamless, integrated manner. This scenario is prevalent in hybrid configurations, where organizations may choose to maintain certain mailboxes on-premises while migrating others to the cloud. This setup allows for features like shared calendars, free/busy information, and unified messaging capabilities, enhancing communication and collaboration between users located in different environments. It facilitates a gradual transition to the cloud, promoting flexibility for organizations that may not want to perform a full migration at once. While the other options touch on different aspects of server use and management within an organization, they do not accurately capture the concept of coexistence, which specifically entails the integration and interoperation of on-premises and cloud-based Exchange systems.
