Part 1: Do You Need to Repair PST?
If your Outlook application displays an error message, that may or may not be due to a corrupted PST file. Outlook error messages can be due to many things, but corrupted PST data files are certainly among the most likely factors. Some Outlook error messages include specific references to PST files. These are some examples of PST error messages:
- “The file xxxx.pst is not a personal folders file.”
- “Unable to display the folder. The file xxxx.pst could not be accessed.”
- “xxxx.pst can not be accessed – 0x80040116.”
- “File xxxx.pst could not be accessed. Data error. Cyclic redundancy check.”
- “The file xxxx.pst cannot be opened.”
When Outlook displays an error message like one of the above, you almost certainly need to repair a PST data file to resolve the issue. If Outlook displays an error message that doesn’t include a PST reference, you might need still need to repair a PST file. However, there might be other potential resolutions for the issue.
If you’re not sure, try some alternative resolutions to PST file repair first. If none of them work, however, then a PST fix might be required to resolve the issue. In which case, you’ll need to find a best PST file repair tool.
Part 2: Why Use PST Repair Software?
Outlook has an Inbox Repair Tool (otherwise SCANPST.EXE) that can fix corrupted PST data files. That utility is located within the default C:\Program Files (x86)\Microsoft Office\root\Office folder. So, you can try repairing a PST data file with the Inbox Repair Tool first.
However, the Inbox Repair Tool isn’t entirely reliable as it only fixes relatively minor PST corruptions. SCANPST isn’t reliable when it comes to repairing more seriously corrupted PST data files. So, it can’t always fix more heavily corrupted PST files.
Therefore, some users will need third-party PST repair software when the Inbox Repair Tool isn’t sufficient. The best Outlook PST repair software packages incorporate much more comprehensive utilities than the Inbox Repair Tool. These are some of the best PST repair software for Windows.
