I wanted to recover OST in Outlook for a long time but I was not able to find any safe software which would not damage the data of my post file. Then my friend told me about the eSoftTools OST to PST Converter Tool which I used and I got very good results. Apart from this, its features are also very useful. Apart from this, this software is available in many languages, so it can be used by both English and non-English users. Using this tool, you can convert OST files to PST, EML, MSG, EMLX, HTML, and many other files. This tool can be downloaded on any Windows operating system. Also, a free option is given in it, using which you can recover 25 emails for free.
