Outlook’s Personal Folders (PST) files are essential for storing your email messages, contacts, calendar events, and other important data. However, these files can become corrupted or damaged, preventing you from accessing your critical information. If you’re using Windows 7 and are experiencing issues with your Outlook PST file, there are a few methods you can try to repair it.
Using the Built-in Inbox Repair Tool (ScanPST.exe)
Microsoft provides a handy utility called the Inbox Repair Tool, also known as ScanPST.exe, to help you repair minor PST file corruption, errors, and inconsistencies. Here’s how to use it:
Close Outlook.
Press Windows R, type %programfiles%/Microsoft Office/ and press Enter or click OK.
Open the Officexx or root/officexx folder and locate the ScanPST.exe program.
Double-click on the program file to launch it.
Click Browse to select the corrupt PST file for the scan. The PST file is usually located in the %localappdata/Microsoft/Outlook folder. After selecting the PST file, click Start to initiate the scanning process.
After the scan, the tool will display if the PST file has errors and inconsistencies. Click the Repair button.
The tool will create a backup of your PST file with the .bak extension and then repair your original PST file.
After a successful repair, you can close the SCANPST program and launch Outlook.
You should now be able to access your emails and send/receive new emails.
Using a Third-Party Outlook PST Repair Tool
While the ScanPST.exe tool is useful, it may fail if the PST file is severely corrupt, oversized (larger than 2 GB), or encrypted. In such cases, you can use an advanced Outlook PST repair tool, such as Stellar Repair for Outlook, to repair severely damaged and/or large PST files with complete integrity and precision.
This advanced Outlook PST repair tool is designed to handle complex scenarios where ScanPST.exe fails to repair the file. The tool also comes in handy when you don’t have access to the SCANPST tool. It is easy-to-use and provides advanced features, such as:
Repairs large PST files up to 50 GB.
Multiple file saving options, such as new PST, HTML, PDF, EML, MSG, and RTF.
Directly export the mail items from the repaired PST file to any Microsoft 365 (Office 365) or on-premises Exchange Server mailbox in a few clicks.
Advanced filters to filter out spam/trash messages.
Using a third-party tool like Stellar Repair for Outlook can be particularly useful when the built-in Inbox Repair Tool is unable to fix the issue, or if you need to repair a large or severely damaged PST file.
Tips to Prevent PST File Corruption
Prevention is always better than cure. To prevent instances of PST file corruption or damage, it is recommended to:
Regularly back up your Outlook data, such as emails, contacts, attachments, etc. to a local PST file using the Outlook import/export wizard. This will help you avoid data loss in the event of PST file corruption.
Scan your Outlook data file, such as PST, every once in a while to keep a check on minor errors and inconsistencies. By doing this, you can catch and fix issues before they become more severe.
