How to Convert MBOX file into EML File?

Summary: The MBOX file is quite a popular one, with many email clients using it to store their data. However, it has a few limitations which prompt people to switch from it to other formats like EML. What are these limitations and how can users convert Thunderbird MBOX to EML format is the focus of this article.

MBOX maintains an extensive text file that stores all messages in a string form, but it contains different files for different mailboxes. For instance, for Outlook, MBOX will maintain a single file for all emails, and a separate file for the emails on Gmail. UNIX had been the most predominant user of MBOX files but today, Mozilla Thunderbird, Qualcomm Eudora, and Microsoft Entourage are also using MBOX as their primary data file format.

What difficulties do users face with the MBOX file format?

MBOX is an open source file format which is used to store email messages in the String format, and it is used by many email client applications like Thunderbird, Opera, Apple Mail, and more. But still, users face many difficulties with MBOX file format as compared to another file format, the EML file format. Some of these difficulties are listed below:

  • It doesn’t allow users to save individual email messages.
  • MBOX File format doesn’t get indexed with Windows Desktop Search easily. Whereas EML file format gets indexed quite easily making it convenient for the users to search emails quickly.
  • MBOX is not compatible with many email clients whereas EML File format is compatible with email clients such as Outlook and Windows Live mail, making it more useful for the users.
  • Like MBOX, the EML file also saves email messages and it is mainly associated with Microsoft Outlook. The EML file, in addition to the text, can also organize the attachments.
  • The formatting of an EML file is similar to that of an MHT file, and this feature makes it possible to open an EML file in the Internet Explorer. You can also open an EML file by using a text editor, for instance, Microsoft Notepad. This is not possible with MBOX file format.
