I have used all MBOX Converter tool that converts MBOX to NSF paid and free ones but some were not secure or some proper not working. But one day I found eSoftTools MBOX Converter softwarewhile searching on Google and I bought it. When I opened this software, I did not face any problems because its graphic and the user interface is very simple. its special thing is that eSoftTools MBOX Converter software works properly in all versions of windows like windows 7, windows 8, windows 8.1, and Windows 10. This software supports multi-language like English and non-English. And the facility of 24*7 technical help has been provided in this tool but most of the companies that manufacture MBOX Converter software do not provide a 24*7 facility. But I haven't faced any technical problems with eSoftTools MBOX Converter software yet. These tools convert Mbox files to NSF 100% secure and safe in a few minutes.
