SysTools MBOX Converter Review- MBOX Converter Tool

Why do we need an MBOX Converter? What is it used for?

A professional MBOX Converter, as the name implies, is mainly required for converting MBOX files into other file formats. MBOX is the open-source standard for email mailboxes. It is the native file format for more than 20 email clients ranging from Windows, Mac, and Linux. A few examples would be Mozilla Thunderbird, Apple Mail, Opera Mail, Entourage, Eudora, etc. Even web-based email services such as Gmail export data in an MBOX file.

Unfortunately, not all email clients support it. So, if a user wishes to access this file in email apps such as Outlook, it will be impossible to do without MBOX conversion utility. A few situations to help understand the necessity of MBOX converter are explained below:

Email Migration

Consider a scenario where a user decides to switch from an MBOX email client to other applications such as MS Outlook. Since Outlook does not support the MBOX file, it needs to be converted into PST format. An MBOX converter is required for such scenarios. The same holds true for migration to other clients such as IBM Notes, WLM, Outlook Express, etc.

Opening orphan MBOX files

  1. A user has old MBOX files from the past that he/she needs to access.
  2. Or, someone, a client/ employer/colleague, provides you with MBOX files containing the information required for your professional duties.

A person using typical MBOX email clients such as Thunderbird can access the orphan MBOX files. But not those who use Outlook, IBM, Outlook Express, and other email clients. These files, first, must be converted to a compatible format for use.

Accessing extracted Webmail data

Webmail clients such as Gmail allow their users to download their data in an MBOX file. The same is true for some cloud backup services such as Datto and web hosting platforms. To access these files in preferred applications, sometimes converting MBOX is necessary.

The requirement of Single Files per Email

MBOX stores multiple email messages in a single file. For those who wish to extract this data in a single file format such as EML, MSG, HTML, etc. using an MBOX converter is the optimal choice.

Other Scenarios:

  • To use emails for legal purposes such as producing emails in court, and forensics, converting mailboxes to PDF is a widely used choice.
  • A good MBOX converter also helps in extracting only the attachments from the MBOX files.

With a professional tool at your disposal, you can easily export the data without having to worry about the technical aspects of migration.
