Continuous .pst corruption (Scanpst does not work)


  • We have several users that are getting the error to quit Outlook and run the Inbox Repair Tool. This is happening several times a day with these customers. I have run a scanpst fixed the errors and got the .pst files back up and running but only for a short time. Is there a fix for this due to its spreading like wildfire throughout the building? We are using Outlook 2007pro

  • Hi,

    Could you please provide detailed error information, it would be helpful narrow down this issue.

    For your description, the problem may occur if Outlook data file(.pst) corrupted, you can remove the old .pst file, and create a new one test if it helps.

    1. On the File menu, point to New, and then click Outlook Data File.
    2. Select Office Outlook Personal Folders File (.pst), and then click OK.
    3. In the File name box, type a name for the file, and then click OK.
    4. In the Name box, type a display name for the .pst folder, and the click OK.
    5. Click Tools, point to Account settings..., and click Data Files tab.
    6. Select the new Outlook Personal Folders File (.pst), and click Set As Default button.
    7. Select the old Outlook Personal Folders File (.pst), and click Remove button.
    8. Click Close button, and exit Outlook.

    If the problem does not appear in the new Outlook Personal Folders File (.pst), you can import Outlook items from a Personal Folders file (.pst), see How to manage .pst files in Microsoft Outlook ,

    If the problem still persists, the problem may related to other function, you can also visit  this Microsoft website:

  • The error being given is:

    "cannot start microsoft office outlook, cannot open the outlook window, the set of folders cannot be opened,. errors have been detected in the file H:/User/email" (name has been changed for user protection)

    use the inbox repair tool (scanpst.exe) to diagnose and repair errors in the file.

    We have tried going into creating a new .pst file, Importing the old .pst files  to the new one and then deleting the old. Then with the new .pst file created setting it at default, only problem was with that is the very next day not only did that .pst file get corrupted but, the rest of them did too. We have users here that have anywhere from 5-30 .pst files. We also tried creating a new .pst file but not setting it to default. This method made it so it took 2 days to corrupt instead of the next day, and it was only that .pst instead of all of them. 

    We also have the customers that no matter what we do or change for some reason they are being corrupted a minimum  of 2 times a day. With these customers we have tried changing their .psts, we have tried deleting all .pst files except for the default, we have tried going in and recreating the users account, we have completed profile rebuilds through our servers, we have even tried to switch the user from thin to thick client and vs versa, still the same problem day in and day out.

    Something I forgot to mention is I have made sure that with every user that they are completely logged out of Outlook before starting.

    If there is anymore information you may need please let me know. Any help at this point would be greatly appreciated.

    Please run following commands test if it helps:

    outlook.exe /resetfolders   Restore missing folders at the default delivery location.

  • Hi,

    If used Cached Exchange Mode, please turn it off test this issue.

    Another way, please create a new Windows profile, we can follow the steps in the articles to create a new user account to test the issue. If the problem does not occur in the new user account, some settings in the old account are corrupted. We can copy the main user files from the old account to the new account, delete the old account, and then continue using the new account.

    Windows 7:

  • We dont use exchanged mode unless on a thick client and we have tried this method on our thick clients as well.

    I have rebuilt customers profiles in which the process we have calls to create a new profile through Outlook. The only change it made was it took a couple of days but the corrupt .pst files still came back.

  • We aren't allowed to due to Scanpst is the only approved .exe we can run.

    The issue was with another program running through Outlook. Once they fixed that issue the issue at hand was resolved

  • Hello There,

                          Any problem related to Outlook depends on PST. If your PST file is corrupted, lost or deleted then your Outlook will not work. If your PST files is corrupted then you need to recover it, so first check that your PST files is in place or not. If it is not and you are sure that it got deleted then you can recover corrupt PST and later you can repair it using file repair software.

  • I'm assuming you are storing your PST files on a network drive as it says H: above. While many companies do this I don't think it has ever been supported by Microsoft. I would check to see if there are problems on your network or your network store. Easiest way would be to move those files over locally and see if the same corruption occurs. I think you will find that it does not.

  • Download this Outlook Repair Toolbox from the and install it on the system in which Outlook PST is corrupt.

    Close Outlook application if you have opened it and run the software. In the main screen, you will see these options i.e. ‘Open PST’, ‘Find PST’ and ‘Select Outlook Profile’. Go for appropriate option based on your situation. Then the software will scan selected PST file for all its attributes in order to repair. Then select the desired location where you want to save the new PST after repair process and next click on repair. When repair process ends, you can access the repaired PST data in a new PST file.
