Dear EE,

I'm looking for a solution over the internet on how to repair or fix an oversized PST file, its size is almost 4GB already, in whereas SCANPST.EXE can't repair it anymore...
Any other advise on how to resolve this file? I tried to look on the internet for the free softwares, but failed to find anything...

BTW, I'm using Outlook 2007.
Hope to hear any advise from anyone of you...

    Hello stiebel,

    I have done abit of browsing and found something that may be of some use to you in your situation. Microsoft have also got a PST and OST crop tool that you could use, located here
    The crop tool just just as it suggests: it crops, or cuts, the size of the PST file by a specified amount to make it smaller. It makes it small enough to run scanpst on which can recover the contents of the PST. Any messages in the portion of the PST that was cut is lost. This is all I have been able to find however that would assist you in this issue. Hope it helps

    @ckivml: The program asked me to register in order for me to save the file. What can I do? I can't save the file if I don't register.
    Please advise...

    Because PST file is complex, you can hardly find a free tool that will solve your problem. The only one I know is scanpst, but it failed on your case.

    Anyway, you can try the alternative solutions at and use the one that is affordable.
