To Import MBOX files into Outlook manually, you need to use an intermediate email client like Thunderbird, as Outlook does not support MBOX files natively. First, import the MBOX file into Thunderbird by selecting it via the "ImportExportTools" add-on. Once imported, configure an IMAP account in Thunderbird that syncs with Outlook. Finally, drag the emails from the imported folder to the IMAP folder, which will synchronize them with Outlook.

However, the manual process is time-consuming, complex, and requires technical expertise. It is prone to data loss, incomplete migration, and difficulty handling large MBOX files. Additionally, installing and configuring multiple email clients can be cumbersome, especially for users with limited technical skills.

It ensures data integrity, supports bulk conversion, and preserves folder hierarchy and attachments. The tool is user-friendly, requiring no technical knowledge, and significantly reduces the risk of errors.
