How to convert OST to PST format?
Before you can try any 3rd party paid tool for OST to PST conversion, you must try few easy manual tricks which are as effective as a professional converter tool. The manual tricks don't require any such paid software or any cost. I'm sharing a blog post here in which you can find detailed information about OST to PST conversion manually - wordpress.semnaitik.com/2013/10/29/convert-ost-to-pst/
If the manual tricks fail or don't work, then only you should try a professional tool. Generally manual tricks don't work with corrupt OST files. In such situation, you must try a tool that can support conversion of corrupt OST files as well. The OST Recovery software is the best solution one can have if he/she is having corrupt OST files. It first scans corrupt OST file, recovers data from it, and then saves them into a new PST file. You must download its demo version for free evaluation.
