What is the purpose of the "Mailbox Import Export" tool?

The "Mailbox Import Export" tool is designed specifically to facilitate the import and export of mailbox data using PST (Personal Storage Table) files. This capability is essential for administrative tasks such as migrating mailboxes between different servers or performing backups of mailbox content. By using PST files, administrators can efficiently transfer large amounts of mailbox data, which is crucial for data management strategies, compliance with legal requirements, or organizational policies.

The tool allows administrators to export a user's mailbox to a PST file, easily archiving data or moving it to a different environment. Conversely, it also enables the import of PST files back into Exchange, allowing restored or previously archived mailbox content to be reintegrated into a user's mailbox. Therefore, it serves a pivotal role in maintaining and managing mailbox data integrity within Microsoft Exchange Server environments.
