I have been looking for such software on the Google Search engine that Converts my MBOX files to PST without any problem. That's when I got eSoftTools MBOX converter software on the eSoftools.com website. The software is 100% secure so that there is no chance of malware and virus threats to come in any windows operating system like windows 7,8,8.1 and 10.
