Tested Ways: Convert Thunderbird (mbox) Files to Outlook (.pst) Free

Summary: Thunderbird and Mozilla Mail store their mailboxes in MBOX files. However, users are choosing better email platforms than MBOX. User-friendly GUIs, enhanced security, and more are desired. MS Outlook provides anti-spam, password security, emailing, and more. All mailbox data is stored in PST files. Users convert MBOX to PST for that reason.

MBOX to PST transfer methods will be covered in a future guide. We will also discuss BLR Tools MBOX Converter, an automated solution. Users can mass convert MBOX to PST without loss. Before proceeding, understand the distinction between MBOX and PST files.

MBOX vs. PST file differences

MBOX File:

• MBOX, or Mailbox, manages messages.
• MBOX files can be opened by Apple Mail, Mozilla Thunderbird, Eudora, Opera Mail, etc.
• MBOX stores all data in one database, which might lose data.
• Many email clients store and transport data in MBOX format.

Outlook PST Files

• MS Outlook uses the PST file format to store mailbox items.
• Outlook accepts PST files.
• PST files store data securely with a broad range of capacity.
• PST files are unique to MS Outlook and cannot be opened elsewhere.

The table above should clarify MBOX and PST file differences. We’ll explore MBOX-to-PST conversion now.
