Manual Approach for Scanpst Not Working Fix

IT administrators & enterprise users can attempt several native troubleshooting methods to resolve their ScanPST execution failures. We have discussed the most effective manual fixes to repair Outlook data file available within the Windows & Outlook environment.

Method 01: Locate the Correct ScanPST.exe File

Running ScanPST from an incorrect installation path is one of the primary triggers behind execution failures. 

1. Completely shut down Microsoft Outlook before you proceed.
2. After that, open File Explorer & navigate to the Outlook installation directory.
3. You need to locate ScanPST.exe using the appropriate path for your Outlook version:
   • Outlook 2019/2016: C:\Program Files (x86)\Microsoft Office\root\Office16\
   • Outlook 2013: C:\Program Files (x86)\Microsoft Office\Office15\
   • Outlook 2010: C:\Program Files (x86)\Microsoft Office\Office14\
4. Thereafter, double-click ScanPST.exe to open the repair utility.
5. Finally, press Browse, select your PST file, & simply hit Start to begin the scan.

Method 02: Run ScanPST Multiple Times if Scanpst.exe Not Responding

Severely corrupted PST files may require repeated scan cycles to achieve a successful repair outcome.

1. Open ScanPST.exe from the verified installation directory.
2. Click Browse and select the target corrupted PST file.
3. You need to hit Start to initiate the scan & allow the process to finish.
4. Once the scan concludes, you have to simply press Repair in order to apply the necessary fix.
5. Repeat the scan & repair cycle 3 to 5 times until the tool reports no remaining errors.

Method 03: Reduce PST File Size Before Scanning

Oversized PST files are a frequent cause of mid-scan ScanPST failures. The process to compact the file prior to scanning can eliminate this issue.

1. Open Microsoft Outlook >> File >> Account Settings.
2. Select the Data Files tab & simply click on the relevant PST file.
3. Click Settings and choose Compact Now to initiate file size reduction.
4. After compaction finishes, close Outlook and relaunch ScanPST.exe.
5. Select the compacted PST file and click Start to proceed with the repair scan.

Method 04: Create a Backup Before Running ScanPST

The process to secure a backup copy of the PST file prior to any repair attempt safeguards against permanent data loss in the event of a scan failure.

1. Open File Explorer & simply navigate to the PST file storage location.
2. You need to right-click the PST file & select Copy.
3. Paste the file into a dedicated backup folder on your local storage drive.
4. Once the backup is secured, open ScanPST.exe & proceed if scanpst not responding.

Limitations of the Manual Method:

• Cannot repair severely corrupted or deep-level structural PST damage.
• No guarantee of complete data recovery after multiple scan cycles.
• Oversized PST files cause frequent mid-scan execution failures.
• Recovered files may still contain missing or inaccessible mailbox items.
• Time-consuming process for large enterprise PST deployments.
• Does not support batch repair of multiple PST files simultaneously.
