If you don’t know what Outlook is, (then where have you been!?) It’s an application that lets you manage multiple email accounts. But that’s not all it's good for… It also works with Microsoft Exchange Server and Microsoft Sharepoint Server for multiple users in an organization to share mailboxes and calendars, Exchange public Folders, etc…  Once you start using the application you’ll find turning to the app more and more for tasks other than just viewing your mailbox.

Finding your Outlook app or folders not functioning properly is never a pleasant experience, that’s why Outlook comes with an Inbox Repair tool (scanpst.exe) to diagnose and repair errors in the file.  Use Inbox Repair tool to recover corrupted files in Outlook’s Data File (.pst and .ost). It can help keep the integrity of that data file intact.

How to find the Inbox Repair Tool?

The location of inbox repair tool depends on the version of Microsoft Outlook the user has and whether he is using a 64-bit or 32-bit version of Windows.

There are many different versions of Microsoft Outlook and depending on that the location of the Scanpst.exe file may differ.

Outlook 2007-32 Bit Windows-> C:\Program Files\Microsoft Office\Office12

Outlook 2007-64 Bit Windows-> C:\Program Files (x86)\Microsoft Office\Office12

Outlook 2010-32 Bit Windows-> C:\Program Files\Microsoft Office\Office14

Outlook 2010-64 Bit Windows-> C:\Program Files (x86)\Microsoft Office\Office14

Outlook 2013-32 Bit Windows-> C:\Program Files\Microsoft Office\Office15

Outlook 2013-64 Bit Windows-> C:\Program Files (x86)\Microsoft Office\Office15

Errors were found and can be repaired.

Steps for Repairing Process:

  • Before starting the repair process ensure that there is a backup of the pst-file.
  • After the Repair button is pressed, the actual repair process will start. This process can take quite a while depending on the size of the pst file.
  • Sometimes when the repair process starts, it will show “not responding” in the title bar. But actually, it is not hanging but making a copy of the pst file in the background or already has started the repair process.

Repair completed!

If the process goes correctly, a dialog box “Repair complete” will appear after some time.

Being developed by Microsoft Inbox Repair Tool is compatible with fixing problematic issues with Outlook data files, but still, it is a free tool and it has its limitations. When the problem becomes drastic it has a lesser success rate of repairing a corrupt file. For example, in cases where the PST file is deleted or emptied due to a virus attack, the free tool fails to recover. Additionally, there is no guarantee that the free tool will complete all phases of the repair process, it could halt in the midway. So for safety purposes, it is advisable for users to use Remo's alternative inbox repair tool- a more advanced PST Repair Tool rather than going for a free aid because using Scanpst.exe has some adverse effects too and for your good, try the best rather than regretting later.
