MBOX is a popular file format used by prominent email clients, such as Thunderbird, Apple Mail, Eudora, Entourage, and others, to store mailbox data, such as emails, contacts, attachments, etc. But Microsoft Outlook does not support the MBOX file format. So, there is no direct way to import MBOX file data into Outlook. You first need to convert the MBOX file into Outlook-supported PST file format and then import it into the application.

What is an MBOX File?
MBOX is a container file format that is used to store various mailbox items, such as emails, attachments, contacts, calendars, and more. There are several email clients that uses this file format to store the mail items. The MBOX file can be opened in an MBOX-supporting email client, such as Thunderbird or using any text editor, such as MS Notepad, GitHub Atom, etc.
What is a PST File?
PST or Personal Storage Table is a type of file format used by Outlook to store the mailbox items, such as emails, contacts, appointments, journals, etc. It is created automatically when the POP3 account is configured in Outlook or when the user exports the mailbox data. This file is used to move the Outlook mailbox data to another system or import it into another Outlook profile or Office 365 account.
