I was searching for a reliable OST to PST Converter as I have faced many issues earlier using the manual techniques. Came across the DRS OST to PST Converter. Must say, the performance of the software is really smooth and I was able to batch convert all my important Exchange OST data to Outlook PST format. Even the interface is so easy that a novice user can simply run the software without necessarily requiring any technical expertise. The software is a highly recommended one.
