At first, I was trying to find a free tool to convert OST file to Outlook. But after wasting my half-day, I got to know there is no such free tool and most of them cost around 40 to 50 USD. After a lot of confusion, I discussed with my cousin and he suggested me to try this tool from eSoftTools. It was the most affordable tool (29USD) among all. With this, I was able to export all mailbox components without a miss. In case if you are reading my feedback then give this tool a try. I am sure that you will definitely like it and will share your review here in a similar manner
