mailbox mapping

Mailbox mapping is a feature in migration tools like Stellar Migrator for Outlook that helps IT administrators and small businesses move PST and OST mailbox data into Microsoft 365, Exchange Server, or new PST archives. The mapping process simplifies the transfer by allowing users to define which source mailboxes correspond to which target destinations, reducing the complexity of manual CSV configuration. This approach is designed for those who find Outlook's built-in import wizard too limited for batch jobs and Microsoft's PST Import Service too administrative. Mailbox mapping in such tools aims to make migrations more accessible for IT generalists handling multiple mailboxes.
