MBOX is the generic file format that saves a collection of email messages from a folder in a database file. New messages are appended to the end of the file. Many open-source email clients use MBOX files to store their mailboxes. These clients are Apple Mail, Mozilla Thunderbird, SeaMonkey, Power mail, etc. The user can employ these email clients to manage their email communication. If a business requires an email client that provides more benefits than mere email communication, then MS Outlook is the best candidate.

MS Outlook can create unlimited accounts to configure a variety of servers and provide them additional features to use contacts, calendar, appointments, journals, etc. But, to use Outlook, the MBOX users need to convert MBOX files to Outlook-supported PST format.

Why is MS Outlook Preferred Over MBOX Email Clients?

Before going for the conversion, it is good to understand the advantages of PST over the MBOX format:

  • PST supports multiple types of data
    MBOX format is suitable only for email messages as it has a simple format. But the PST format can support emails, contacts, tasks, calendars, notes, and more mailbox items.
  • Advanced format
    PST format is very advanced for storing mailbox data systematically. But the MBOX format is very simple, and emails are saved sequentially in a text file.
  • Outlook supports Exchange accounts
    MS Outlook is designed for Exchange connectivity. So, it supports all Exchange versions, including Exchange 2019 and all Office 365/Microsoft 365 plans. And it is possible to work in offline mode in Outlook.
  • More control and better security features
    Outlook provides more control for users and offers advanced security features for emails and attachments such as Anti-spam, password protection, etc.
  • Frequently updated
    Outlook and PST format are updated periodically to meet the new communication requirements. MBOX and its email clients, being open-source, are not updated periodically.
