OST Converter helped me to convert OST file to MBOX format as I have recently chosen Thunderbird as my email client. I loved the instant conversion rate of this application so I want to recommend others to utilize it.

Before getting the license of OST File Converter, I have compared it with lots of utilities but this one application offers multiple export options with the rapid conversion rate so I finally invested in this application and I am happy that I took the correct decision.
