How can you be sure of the OST recovery capabilities of Kernel for OST to PST before buying it? You can test it by downloading a trial version of the software. Download the trial version and use it to recover your inaccessible OST files. But keep in mind that the trial version allows you save only 25 items form every OST folder. However by using the trial version, you can have an idea about the features of the software. If required, you can purchase the software later.
