As per expert’s opinion, the Manual method is efficient for conversion of MBOX file into MS Outlook PST file, but it doesn’t give 100% assurance for safe migration.
So, users should try advanced MBOX to PST converter for safe migration. I have found that some vendors are providing a free demo for testing the performance of the software. In my knowledge, You can get a free demo of MBOX converter tool from: http://www.stellarinfo.com/email-tools/mbox-to-pst-converter.php
