Originally used by Unix applications only, MBOX files are now supported by Apple Mail on MacOS or cross-platform mail clients, such as Thunderbird. While some clients allow exporting MBOX mailboxes to other formats, it’s easier to convert original files with a dedicated tool and MBOX 2 PST is a good example.

Working with MBOX 2 PST is not complicated at all, since it features a one-window interface that comprises all the available options, with no other menus than the classic “File” and “Help” ones.

The instructions in the GUI make everything extremely intuitive. First, you must import the MBOX files you want to convert by selecting a folder where the data is located. There is no option to import individual MBOX files as input, but that should not be an issue, since MBOX 2 PST can look for compatible MBOX files inside the source folder and its subfolders. In other words, recursive search is available and, what is more, you get to preserve the original folder structure during conversion.

The next step is to select the destination. There are two available options at this point: either the default Outlook storage or an existing or a new PST file. You get to select the name of the target folder or browse for the PST file to replace. And, in case the output is password-protected, you are prompted to enter the password.

The main window also encompasses a log window that displays information about all the actions of the MBOX 2 PST converter.

Another perk of MBOX 2 PST is that it can batch convert MBOX files to PST format even in batch scripts, since it comes with additional command line options.

The MBOX 2 PST application performs all the conversions in offline mode, not sending any data to a server to endanger your privacy, which is the main risk of using an online email conversion tool. All your sensitive information, such as messages, contacts, tasks, notes are converted securely, with no limit on the size of the input.
