Being developed by Microsoft Inbox Repair Tool is compatible to fix problematic issues with Outlook data file, but still it is a free tool and it has its limitations. When the problem become drastic it has lesser success rate of repairing a corrupt file. For example in cases if the PST file is deleted or emptied due to virus attack, the free tool fails to recover. Additionally there is no guarantee that the free tool will complete all phase of repair process, it could halt in the midway. So for safety purpose it is advisable to users to use Remo's alternative for inbox repair tool- a more advance PST Repair Tool rather than going for a free aid,  because using Scanpst.exe has some adverse effect too and for your good, try the best rather than regretting later.
