    Yes, Mike is right. Sometimes you need to run the Scanpst.exe 3 to 4
    times to repair the pst file. But firstly , you need to identify the
    version of Microsoft Outlook that you are using. The size limitation for
    .pst file is 2 GB in Microsoft Outlook 2002 and its earlier versions .
    Also Scanpst.exe is not able to repair the .pst file which have the size
    of more than 2 GB. So it is necessary to know the version of the
    Outlook and reason for .pst file corruption. Once you get the
    information then either Scanpst.exe or an efficient Outlook PST Repair
    Tool can be used.

    Have you tried importing the PST file into an empty Outlook?

    You should run "SCANPST" for a few times in a row. Sometimes problems get fixed after the 4th or 5th run. Also you can try changing the first Bits of the file using a HEX-Editor and then run "SCANPST" again (as described here:

    Other then that you will have to use some PST Recovery software e.g.
    Stellar Phoenix PST Recovery (
    DiskInternals Outlook Recovery (

    I usually get the best results using the Stellar Phoenix software but I strongly suggest you to evaluate [using the Demo/Trial] of multiple solutions since results vary quite a lot sometimes.
