Method #3: PST file recovery with the Microsoft Inbox Repair tool

  • Outlook cannot open your data file.
  • Outlook is unable to open the collection of folders.
  • Outlook data files might be corrupted.

The Inbox Repair Tool does not connect to or analyze any data within an Exchange mailbox. Its sole purpose is to search for errors or corruption and, if found, it provides the necessary capability to fix those errors.

Before fixing corrupt PST/OST files, you may need to find your Outlook Data Files in Microsoft Outlook by taking the following steps:

1) Within Outlook, select File, then Account Settings, and click on Account Settings.
2) Next, click the Data Files tab.
3) All Outlook Data Files (.PST) and Offline Data Files (.OST) will be listed, along with the account name associated with the files.

Now to fix an Outlook (.PST) or (.OST) file, close Microsoft Outlook first, and then navigate to one of the following locations based on the Outlook versions that you have:

> For Outlook 2019: C:\Program Files\Microsoft Office\root\Office16
> For Outlook 2016: C:\Program Files\Microsoft Office\root\Office16
> For Outlook 2013: C:\Program Files\Microsoft Office\Office15
> For Outlook 2010: C:\Program Files\Microsoft Office\Office14

Please note that during the repair process, a backup file is generated. If you would like to modify the default name or location of the backup file, please either enter a new name or click “Browse” to locate the desired file.

The Inbox Repair tool creates a backup copy of the original file in the same folder, with the same name but with a .bak extension. If you want to retrieve items from the backup (.bak) file, you should make a duplicate of the backup file and rename it with the bak.pst extension. For example, you can rename it as jack.smith01@outlook.com.bak.pst.

Next, open Microsoft Outlook and import the bak (.PST) File. Go to FileOpen & ExportImport/ExportImport from another program or File as shown in the figure below.
