Repair Outlook PST file: scanpst.exe

How to use Scanpst.exe to repair Outlook data files

Inbox RepairScanpst (aka the Inbox Repair tool) is found in your Office installation folders, usually C:\Program Files\Microsoft Office\OfficeXX, where XX is your version of Office. In Vista and Windows 7 64-bit, the folder is C:\Program Files (x86)\Microsoft Office\OfficeXX.
Note: The scanpst icon is a broken envelope. This is supposed to indicate that it works with broken messages. It does not mean the application is broken.

Office 2010 Home & Business ‘Click to Run’ users: Scanpst is not available. With Click to Run, Office is installed in a virtual space on the Q drive and you can’t access files on this drive letter. If you aren’t sure if you are using Click to Run, check File, Help in any Office 2010 application.

Replace XX in the following to match your version (the textboxes below are editable), then copy and paste it into the Address bar of Windows Explorer and press enter to open ScanPST.
Outlook 2010 = 14Outlook 2007 = 12
Outlook 2003 = 11
Outlook 2002 = 10
Outlook 2000 = 9
If you are unsure of your version Help, About will list the version in ’12.6310.5000′ format. If Outlook was installed as part of a suite, Help, About in any of the Office programs will have the correct version number.

We also offer the following shortcut you can type or paste into into Start menu’s search field or into the Run command (press Windows key + R to open the Run command). Don’t forget to change the XX to your correct Office version. (You can change the version number in the textbox before copying it.)
If using 32-bit Windows or 64-bit Windows & 64-bit Outlook use:

Using Scanpst.exe

After scanpst opens, click Browse and browse to the location of the PST. Or paste the following line in the File name field and click Open. This will open the PST location in the file browser. (This path works in all versions of Windows if Outlook created the pst in the local application data path. If you moved the pst or Outlook 2010 created the pst file in My Documents, you’ll need to click Browse. )

%USERPROFILE%\Local Settings\Application Data\Microsoft\Outlook

File Browser

Select your PST from the list (most people will have just one) click Open, then Start to begin testing the PST
ScanPST dialog
When ScanPST is finished running the tests, a dialog reports the errors found. If you need to repair the PST, always make a backup.

  1. Hello There,
    The way which you describe for repairing was impressive but this
    Scanpst won't work all the time. If your PST file exceeds from specified size then will face the corruption and in the case Scanpst will not work. And there are lot more reasons like crash is one amongst them in which file could be repaired by Scanpst. Even i have faced the same problem but later i found a way to do Outlook 2010 repair after crash. If you are also facing the same problem then its better to go for this software download. This software will help you for repairing your PST file and will take you out from the problem of Outlook.
