TrustVare MBOX to PST Converter Review 2026: Features, Steps, Pros, Cons & Verdict
By Georgina Selmon 10-08-2026 7
Introduction
MBOX is a mailbox storage format that email applications such as Thunderbird, Apple Mail, Entourage, Eudora, and other MBOX-supporting clients utilise. However, if users wish to transfer archived MBOX emails to Microsoft Outlook for Windows, they can encounter compatibility issues, as Outlook typically handles PST files rather than MBOX databases.
This is where an MBOX to PST converter tool can make the migration process easier. However, users can convert mailbox data to an Outlook-compatible PST file instead of rebuilding mailboxes manually or using an MBOX-capable email client as an intermediary.
In this review, we have reviewed TrustVare MBOX to PST Converter on the basis of its officially documented features, available conversion options, workflow, usability, and restrictions. The purpose is to know whether it is a feasible option for users who want to move MBOX emails to Outlook but still want to keep the essential mailbox information.
Reasons for Users to Convert MBOX to PST
MBOX files are used for email databases, but might be problematic if a user changes to Microsoft Outlook. Outlook has no default option to open a separate MBOX file as a PST mailbox.
Hence, there are several reasons for a user to hunt for an MBOX file migration solution:
- Open old MBOX emails in Microsoft Outlook.
- Combining multiple MBOX files into a format that is compatible with Outlook.
- Migrate several mailbox files without repeating the same process manually.
- Provide access to earlier email archives in an Outlook context.
TrustVare MBOX to PST Converter Tool
This is a Windows-based MBOX to PST conversion software that is meant to export single or multiple MBOX files to PST format. The tool offers batch processing, preview of uploaded mailbox data, selective conversion and retention of email attributes such as CC, BCC, dates, times, text and attachments, according to the official website.
One interesting aspect is that the software is built as a standalone application. Users do not need to install Thunderbird or any other MBOX-compatible email client for the conversion. This tool can make it more user-friendly for users.
Key Features
1. Single and Batch Conversion of MBOX File
One of the most useful features is batch processing. Users can select numerous MBOX files or select a folder including MBOX data to add one mailbox file and do it several times.
2. Supports Multiple MBOX Sources
As per the official description, the software can enable processing of MBOX files from apps such as Thunderbird, Entourage, Apple Mail, Spicebird and other MBOX-supported platforms.
3. Retains Email Properties
This application preserves the following properties: To, From, CC, BCC, Date, Time, Text, and Attachments.
4. Preview the conversion
There is a preview feature available that shows the contents of uploaded MBOX files. This is helpful when the source has more than one MBOX file, and the user needs to validate the selected data before conversion.
5. Folder mode and file mode
The software offers two modes for selecting source data: File Mode and Folder Mode. File Mode is used when users want to pick a specific MBOX file, whereas Folder Mode is used when numerous MBOX files are kept in a folder.
6. Data Conversion using Selectivity
Not all migrations require the whole mailbox database. There are filtering tools so users can decide what data is included in the conversion.
7. No Thunderbird or Outlook reliance
One large advantage is that the application works independently. According to the official website, you can convert MBOX files without installing Thunderbird or any other application that supports MBOX files, and Outlook installation is not necessary for the conversion procedure.
How to Convert MBOX to PST Using this Software
- Download and install the MBOX conversion application on a Windows machine. Once it is installed, execute the software to start the process of mailbox export.
- File Mode is used if you want to add a specific MBOX file. If the MBOX files are saved in a folder together, select Folder Mode.
- Then, click on the Browse option to find the appropriate mailbox data.
- Once the source files are loaded, you can utilise the preview pane to see the available mailbox content. This allows you to review the data selected before you continue.
- Choose the PST conversion option and select the destination.
- Browse to the folder where you wish to save the resulting PST file.
- Finally, click Convert Now to start the MBOX export process.
Once the conversion is done, you can access the produced PST file in a compatible Microsoft Outlook environment.
Why This MBOX to PST Migration Tool is Useful?
The best feature is, of course, the ability to batch convert, preview, selectively export and run independently. For users with only a single MBOX file, the process can be easy, while those with larger archives can take advantage of folder-based and bulk processing.
Another good thing is that the software is expressly intended for MBOX-to-PST migration, instead of requiring users to first convert their emails into some other intermediate format.
Also, the software works with Windows 11, Windows 10, Windows 8.1, Windows 7 and older versions of Windows.

The process is very simple because of its logical steps: Select MBOX files, preview data, Select PST, select destination, and begin the conversion.
Because File Mode and Folder Mode are available, users do not need to take the same strategy for each conversion. If somebody is migrating one mailbox, then they can select a file. If a user is managing many archives, then they can choose the suitable folder.
The interface is self-descriptive and suitable for users without extensive technical guidance.

This is especially the case if you want to make current MBOX data available in an Outlook-compatible PST structure, without going through a complex manual migration.
Final Verdict

A dedicated conversion software can help make the process more systematic, especially when dealing with various mailbox files, attachments and email attributes.
A professional solution is a practical set of features to achieve this aim according to the officially specified capabilities. The most remarkable advantages are batch processing, preview, selectable conversion, compatibility with numerous MBOX sources and independent operation.
