Summary: When the PST file is moved to another location or is corrupted, you may encounter the Outlook error – “The Path Specified for the PST file is not Valid”. In this post, we’ve outlined some easy ways with stepwise instructions to fix this Outlook error.

This error occurs if the PST file doesn’t exist in the specified location or is moved to a different location or it’s corrupted. In this post, we discuss some easy ways to fix this Outlook error. But before proceeding further, let’s see where the PST file is located on your system.

By default, Outlook Data File is located in the following locations, based on the version of Outlook you are using:

Outlook VersionPST File Location
Outlook 2007drive:\Users\<user>\AppData\Local\Microsoft\Outlook
Outlook 2010drive:\Users\<user>\AppData\Local Settings\Application Data\Microsoft\Outlook
Outlook 2019, 2016, & 2013drive:\Users\<user>\AppData\Local Settings\Application Data\Microsoft\Outlook

You can also find the location of the PST file by following these steps:

1. Go to Control Panel > Mail (Outlook) > Data Files

Mail Accounts Settings in Windows

2. Select the PST file and click Open File Location

Note: You can also note the path of the PST file and reach the folder manually.

If you can’t find the PST file in the location configured in Outlook, it means the file is moved to another location from its original location. If you had moved the file intentionally to another location, you may know the exact location. Otherwise, you can search for the PST file by using the Search function in Windows.

If you are able to locate the file, you can move it back to the original location and restart Outlook. This may fix the “Output file not valid” issue. If you can’t locate the file, you can recover it from a backup (if you have it).

If you find the PST file in the original location, it indicates that the PST file is corrupted. In such a case, you need to repair the file to resolve the corruption issues. For this, you can use MS Outlook’s inbuilt repair utility – Inbox Repair Tool or ScanPST.
