Product Review – Stellar Converter for MBOX

I have a few large MBOX files that I want to convert to Outlook PST format. So, for the past few days, I have been looking for a good MBOX to PST converter tool that can easily convert MBOX files to PST, without any data loss.

After doing some research and reading online reviews, I decided to try out Stellar Converter for MBOX. This software can convert MBOX files of several email clients, including Apple Mail, Mulberry, Entourage, Thunderbird, Spicebird, Eudora, Claws Mail, and others into PST in a simple to follow process. All you need to do is select the MBOX file type you intend to convert, proceed to scan the file, and then save it in the PST format.

Main Features of Stellar Converter for MBOX

Here are some key features of the software which I noticed while using it:

  • The software supports 17 MBOX-based email clients.
  • It allows users to preview the converted emails before saving them.
  • There is an option of saving the MBOX data to a new PST file or appending it to the already existing PST.
  • The software also exports MBOX data to Office 365.
  • It allows to save the data in multiple formats, such as PDF, RTF, HTML, MSG, and EML.
  • Option to filter emails for selective conversion.

The Conversion Process – Easy and Quick

The software’s interface is designed in a way that makes conversion process easy, even for people with little technical skills. I am not a tech-savvy person but I had no problems operating the software.

On the software’s main interface, there is a dropdown list containing almost all popular MBOX email clients to select for conversion. In my case, the email client from which I was going to convert was Thunderbird so I selected it from the list.

After this, I selected the file which I wanted to convert. After selecting the file, I clicked the ‘convert’ button to begin the conversion process of MBOX to PST. The software took  a little time to scan the MBOX file I had selected. This wasn’t much of a problem for me because while the scan process was going on, I was able to work on other things, including accessing important applications.

After conversion, it displayed the entire contents of MBOX file in a well-organized format. I noticed that all the components of the MBOX file were fully converted by the software, including contacts, emails, calendars, attachments and even journals. Another really impressive feature was that the hierarchy in which the folders had been arranged, which made the PST import into Outlook very easy. It was easy for me to validate my mailbox components and the entire experience was really satisfactory as per my expectations.

The next thing I did after validating my mailbox data was to save this data. This was done by clicking on the Save button which appears on the main menu. There were actually multiple options for saving the data, which included appending the converted data to the already existing PST or saving as New PST.

In my case, since I was aiming to migrate from Thunderbird to Outlook, I opted to save the data as New PST.

Also, there was an ‘Apply Filter’ feature that helps in converting relevant data only. It allows to exclude/include emails and other items, based on date range and email address.

What you should know if you’re looking to purchase the software?

Stellar Converter for MBOX actually comes with a free demo version which you can try before deciding to purchase the main software. With the trial version, you can successfully convert the mailbox data and then preview it to determine its validity.

There are basically two paid versions of the Stellar Converter for MBOX – Corporate and Technician. The major difference between these two versions is that the Technician version, along with all the features of Corporate version, offers multiple options to save and export MBOX data. These options are HTML, RTF, and PDF. It also allows to export the converted data directly to Office 365.


After using the Stellar MBOX to PST Converter software, I can say it is easy to convert MBOX files to PST. The features of the software really impressed me and the conversion process went smoothly and without stress. I definitely recommend this software to anyone who is looking to migrate from MBOX email clients to Outlook.
