Answer: (B)

The Mailbox Replication Service (MRS) plays a crucial role in the Exchange Server environment, particularly in managing mailboxes across different databases or servers. Its primary function is to facilitate mailbox moves and migrations, enabling administrators to move mailboxes seamlessly from one database to another or even between different Exchange servers. This service abstracts the complexity involved in these operations, ensuring that the mailbox data is properly copied to the new location while maintaining integrity, and providing progress tracking throughout the process. MRS is essential for tasks such as migrating user mailboxes in a hybrid environment, when upgrading Exchange versions, or when consolidating databases after a server change. By handling the intricate details of mailbox replication and ensuring minimal downtime for end users, MRS allows for efficient and smooth transitions without disrupting day-to-day operations.
