Corruption is a big problem that makes the user to face the problem of not opening their MBOX file and the main reasons are- wrong Interface, Wrong Shutdown, hardware failure, power failure and virus infection. Here I am suggesting MBOX to PST Converter software, which complete scan the MBOX file and when found any error, recover it fast and also save it to many formats such as- PST, EML, MSG, RTF and HTML. This tool also transfer the MBOX file of many email clients’ application and convert it to PST file.
