The Inbox Repair Tool

In the Inbox Repair tool, type the path and the file name of your personal folders (.pst) file or click Browse to locate the file by using the Windows file system, and then click Start.
Note If you do not know where the .pst file is located, follow the steps in How to locate, move, or back up your .pst file.

Note The Inbox Repair Tool cannot repair every problem that is detected. In some cases, items may not be recovered if they were permanently deleted or corrupted beyond repair.

Step 3: Recover repaired items to a new .pst file

After you run the Inbox Repair tool, you can start Outlook and recover repaired items. Optionally, you can try to recover additional repaired items from the backup personal folder.

To start, create a new Personal Folders (.pst) file entry in your profile. Then, you can move the recovered items to your new Personal Folders (.pst) file.

  1. Start Outlook. If you use multiple profiles in Outlook, make sure that you select the profile that contains the Personal Folders (.pst) file that you tried to repair.
  2. Press CTRL+6 to turn on Folder List view.
  3. In your Folder List, you should see the following recovered folders:
       Recovered Personal Folders
          Deleted Items
          Sent Items

    Note These recovered folders are usually empty because this is a rebuilt .pst file. You should also see a folder named Lost and Found. This folder contains folders and items that the Inbox Repair Tool recovered. Unfortunately, items that are missing from the Lost and Found folder may be beyond repair.

What the Inbox Repair tool does

When you run the Inbox Repair tool on a Personal Folders (.pst) file, it does the following:

  • The Inbox Repair tool analyzes the Personal Folders (.pst) file directory structure and item headers to try to recover all folders and items.
  • If the Inbox Repair tool recovers the Personal Folders (.pst) file, it means that the repair tool found problems, and repaired what it could.
  • The Inbox Repair tool tries to turn any file into a Personal Folders (.pst) file. For example, if you rename an executable file to “Something.pst” (without quotation marks), the tool changes the file to a mountable .pst file.
  • The Inbox Repair tool makes a backup copy of any Personal Folders (.pst) file before you try to repair the file.



Note 1:
The <locale ID> is a number to identify your language of Office. You can find an overview of the numbers 
here. You need to look in the “LCID Dec” column for the correct number.

Note 2:
When you connect to an Exchange server and need to check your local cache (ost-file) for errors you’ll need to run scanost.exe. You can find this in the same location as scanpst.exe except for Outlook 97/98/2000 and Outlook 2010. These versions of Outlook don’t have the scanost.exe feature. In this case, rename the ost-file to .old and Outlook will rebuild a new cache from the Exchange mailbox.
