SoftStella MBOX Pro

Many popular applications store e-mail messages in MBOX and MBX files, but these formats are not supported by every mail client out there, which is why a conversion utility can often come in handy.
SoftStella MBOX Pro is a fairly straightforward application designed for this very purpose. It enables you to convert mailbox files to PST, MGS, EML and EMLX, and it supports batch processing.

Useful program that can convert all your files in one operation

If you need to extract data from multiple MBOX or MBX files, this application may be exactly what you are looking for. It allows you to load all your files at once and then process them all in one go.
Unfortunately, though, you cannot view a complete list of the imported files once they have been added, and the program does not support drag and drop.

Versatile utility that keeps things simple

Once you have loaded all the files you wish to process, you only need to select the output format and the destination folder. No complex configurations are required, so even novices should have no problems processing their files.
However, it might have helped if you had the option of setting up a custom file naming scheme when exporting e-mails to MSG, EML and EMLX files.

Straightforward application that features a minimalistic user interface

Functionality aside, SoftStella MBOX Pro has a simple, intuitive layout, and there are no complex menus to navigate through. All of the program’s functions are easily accessible from the main window, so first-time users should be able to get the hang of things in no time at all.
If you do need any assistance, however, you can visit the product’s homepage and read the provided instructions or watch the video tutorial that has been made available.
All in all, SoftStella MBOX Pro is a reliable, user-friendly application that provides you with a quick and easy solution for converting MBOX and MBX files to various other formats. It does its job well, but it could be improved further with a couple of additional features.
