Talking about MS Outlook OST files, the best aspect that I always admire about them is it empowers you to carry out offline work very effectively. In fact, it facilitates you to work offline and then synchronize the file once the Exchange server is connected. However, while you work offline with Outlook, it doesn’t mean that you will never ever get encountered with any trouble. One can easily get encountered with a large numbers of conflict items in Offline Storage Table (.ost) file. I too woke up from my illusion, when I faced a very similar situation. Usually, an occurrence of any such incident indicates that OST file has got corrupt and very soon you may loss important data stored in it.
