What is the Outlook Inbox Repair Tool

The Inbox Repair Tool or SCANPST is a free utility provided by Microsoft. It is designed to scan and repair errors in your PST file, which is where Outlook stores your emails, contacts, calendar events, and other data.

When your PST file gets corrupted, Outlook may fail to open or behave erratically. That is when users turn to SCANPST. But if the PST repair tool is not working, the recovery process becomes more difficult.

This is why knowing how to fix Outlook Inbox Repair Tool not responding is so important.

Why Is the PST Repair Tool Not Working

Before jumping into solutions, let us look at the most common reasons why the Inbox Repair Tool is not responding:

The PST file is too large or heavily corrupted
Outlook is still running in the background
Conflicts with antivirus software
Wrong version of SCANPST being used
Lack of administrator privileges
Disk errors where the PST file is stored

Understanding the root cause is the first step in solving the issue efficiently.

Step-by-Step Guide to Fix Outlook Inbox Repair Tool Not Responding

Step 1 Close Outlook Completely

If Outlook is running, SCANPST may not function properly. To make sure it is closed

Open Task Manager using Ctrl Shift Esc
Find OUTLOOK.EXE in the Processes tab
Right-click and choose End Task

Then try running SCANPST again.

Step 2 Run SCANPST as Administrator

Sometimes, the tool needs higher privileges to access and repair PST files. Locate SCANPST on your computer and:

Right-click the file
Select Run as Administrator

Running with admin rights can often fix access-related problems.

Step 3 Make Sure You Are Using the Correct SCANPST Version

The SCANPST tool is located in different folders based on your Outlook version.

Common paths include:

For Outlook 2019 or 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

Make sure you are using the right version for your installed Outlook.

Step 4 Check the PST File Size

Outlook PST files larger than 2 GB can be difficult for SCANPST to handle. To check the size:

Right-click the PST file and select Properties
Review the file size under the General tab

If the file is too large, consider splitting it or using a professional repair tool.

Step 5 Temporarily Disable Antivirus Software

Some antivirus programs interfere with SCANPST. Temporarily disable your antivirus and try running the tool again. Be sure to re-enable your protection after the repair is complete.

Step 6 Move the PST File to a Different Location

Sometimes, the hard drive or folder containing the PST file may be causing the issue. Try moving your PST file to the desktop or another directory, and then run the repair tool on the new location.

Step 7 Use Microsoft Office Repair

If the repair tool still does not respond, your Office installation might be damaged. You can fix it without uninstalling:

Go to Control Panel and open Programs and Features
Click Microsoft Office and select Change
Choose Quick Repair or Online Repair

Once complete, try running SCANPST again.

Step 8 Create a New Outlook Profile

If your Outlook profile is corrupted, it might prevent the repair tool from working.

To create a new profile:

Open Control Panel
Go to Mail and click Show Profiles
Click Add to create a new profile
Set it as the default and launch Outlook

If the new profile works fine, your old one may need to be deleted.

Step 9 Use a Professional PST Repair Tool

When all else fails and the PST repair tool is not working, a third-party solution might be necessary. These tools are more advanced than SCANPST and can repair severe corruption or large files.

Top PST repair tools include:

Stellar Repair for Outlook
Kernel for Outlook PST Repair
SysTools Outlook Recovery

These tools can restore lost emails, attachments, calendars, and more from even badly damaged PST files.
