ViceVersa Tools Releases MSG to MBOX Converter With Two-Way Conversion Support

NEW DELHI - Sept. 5, 2026 - PRLog -- ViceVersa Tools has released the MSG MBOX Converter, a new Windows application for converting email data between the MSG format used by Microsoft Outlook and the MBOX format used by Thunderbird and other mail clients. The application runs the conversion in either direction from a single license, writing MSG files into an MBOX archive or reading an MBOX archive back out as individual MSG files, depending on which direction a given migration requires.

The company built the release around a situation it describes as common in mixed-client offices: an Outlook user moving to Thunderbird needs individual MSG files consolidated into an MBOX archive, while a Thunderbird user moving the other way needs an MBOX archive broken back out into MSG files that Outlook can open one at a time. Rather than offer two separate single-direction utilities, ViceVersa Tools combined both conversions into one program.

The application processes a folder of files in a single job rather than requiring files to be converted one at a time, and folders containing subfolders are processed in full during either conversion. It runs locally on Windows and does not require Microsoft Outlook or Thunderbird to be installed on the machine performing the conversion. Users select the source files, choose the opposite format as the output, set a destination folder, and start the conversion, with the same steps applying regardless of which direction the job runs.

A free trial installer, distributed as ViceVersa-MSG-MBOX-Converter.exe, includes both conversion directions for evaluation before purchase. The Personal license is priced at $39 for one machine with a year of updates. A Professional license extends the same tool to five machines on a lifetime basis for $99, and a Technician license covers unlimited machines for $299, also on a lifetime basis. The application supports Windows 11, 10, 8.1, 8, and 7.
