How to Repair an Outlook PST File That’s Damaged or Corrupt
Issues with Microsoft Outlook’s Personal Folders File format—commonly referred to as PST—have been a huge problem for years. Microsoft knows that, which is why Outlook comes with a built-in tool called Inbox Repair to help you fix corrupted PST files.
In most cases, simply running a damaged PST file through the Inbox Repair tool should be enough to patch it up. But sometimes, you must take extra action to recover lost items.
How Outlook PST File Repair Works
Outlook’s Inbox Repair tool is buried deep within the Microsoft Office installation folder on your computer, so you need to do a bit of digging to get to it. Once you’ve located and launched Inbox Repair, all you need to do is select the damaged PST file to repair it.
Important: Inbox Repair provides an option to create a backup of the damaged PST file. Make sure to select it since you may need a copy to retrieve missing data later on.
1. Completely exit Microsoft Outlook.
2. Open File Explorer. Depending on the version of Windows that you use, navigate through the following folders:
- Windows 64-bit: Local Disk (C:) > Program Files > Microsoft Office > root > Office16
- Windows 32-bit: Local Disk (C:) > Program Files (x86)> Microsoft Office > root > Office16
Note: The folder paths above apply to Outlook 2016, Outlook 2019, and Outlook 365. If you use an older version of Outlook, you must select the Office15 (Outlook 2013), Office14 (Outlook 2010), or Office12 (Outlook 2007) folder instead.
3. Locate the file labeled SCANPST and run it as an administrator.
4. Use the Browse button to select the Outlook PST file that you want to repair.
If you don’t know the location of the PST file, press Windows+S to open Windows Search. Then, search for it by name and include the .PST file extension. You will see the file location within the search results.
Alternatively, open Outlook and go to File > Account Settings > Data Files to view the PST file’s location. Make sure to close the application after that.
5. Select Start. The Inbox Repair tool will check the PST file for issues. That should take some time.
6. Check the radio button next to Make backup of scanned file before repairing and select Repair.
7. Select OK to finish repairing the PST file.
Open Microsoft Outlook and it should automatically start using the PST file without issues. You will find a copy of the corrupted PST file (with the .BAK extension) in the same location as the repaired original.
Recover Lost and Found Files
Sometimes, Microsoft Outlook’s Inbox Repair tool may end up repairing a severely damaged PST file. Suppose the tool fails to place any repaired items in their original folders or locations. In that case, it will lump them into a Lost and Found folder or a set of folders under the Recovered Personal Folders label.
You can recover these items by creating a new PST data file in Outlook and moving the contents from Lost and Found or Recovered Personal Folders into it.
1. Open the Home tab in Outlook. Then, open the menu next to New Email, point to More Items, and select Outlook Data File.
2. Pick the Outlook Data File option and select OK.
3. Specify a location on your computer, enter a name for the new PST file, and select OK.
4. Select the More icon (three dots) to the Outlook window’s lower-left corner and select Folders to switch the Outlook sidebar to Folder List view.
5. Drag the contents within Lost and Found or Recovered Personal Folders into the new data file.
Once you’ve done that, you can choose to remove the Lost and Found folder or the Recovered Personal Folders data file from Outlook.
Recover Additional Items from PST
Suppose you notice any missing items within the repaired data file. if you also can’t find them inside the Lost and Found folder or under Recovered Personal Folders, you can try retrieving them using the backup copy of the original. Basically, you try to import the contents within the file without duplicating any items that the Inbox Recovery tool has already recovered.
1. Copy the corrupted PST file backup to your desktop.
2. Change the .BAK extension at the end of the file name to .PST.
Note: If you can’t see the file extension, open the File menu in a File Explorer window and select Change folder and search options. Then, switch to the View tab and uncheck the box next to Hide extensions for known file types.
3. Open the File menu in Outlook and select Open & Export > Import/Export.
4. Select Import from another program or file and select Next.
5. Select Outlook Data File (.pst) and select Next.
6. Select Browse and select the backup copy of the corrupted PST file (the one that you just renamed).
7. Select Do not import duplicates and select Next.
8. Check the box next to Include subfolders. Then, select Import folders into the same folder and pick the account or data file that you want to import the items into.
9. Select Finish.
Once Outlook finishes importing any items, you must manually confirm if the previously missing items are now present. If not, try running the Inbox Repair tool another time.
Third-Party Outlook PST Repair and Recovery Tools
A cursory search online will reveal lots of paid third-party tools that claim to repair damaged or corrupted Outlook PST files. In almost all cases, though, the Inbox Repair tool should be more than good enough for the job.
