PST errors are all over the place, but they tend to be only a few characters long.They can range from “my password” to “I don’t know my password,” and the biggest reason for them is usually mistyping that last character.In many cases, the problem is that when you’re typing in your password, you end up writing in a different letter than the one you intended it to be. For example, if you want to type your password “l33tst0rm077” instead of “[email protected],” you would write “[email protected]” rather than typing “[email protected]”Even though Microsoft Outlook will most likely detect this and fix it for you if it happens often enough, it is actually quite annoying and frustrating and can potentially mean the difference between a successful PST scan or an unsuccessful one and therefore between a useful recovery solution or not at all.To help make sure your PST files are as error free as possible, we have published a handy guide on how to fix common PST errors that Microsoft Outlook can not identify with its own software: How to Fix Common Errors in Your Personal Surveillance Files »

How to Perform a Basic Repair of a Corrupted PST File
You know that file that’s missing, but you’re not sure what happened. You can open the file in Windows Explorer, but when you look at the contents of the file, you see something like this: PST Error Code: 0x8007005F .You realize that your file is corrupted and it needs to be repaired.The error is caused by one of three things:1. The Outlook PST file is too large – This can happen if your PST files are too big for your operating system (we tend to think of our PST files as being under 5MB) or if your operating system doesn’t support large files (e.g., Windows XP). In such cases, Outlook will show an error message when it attempts to read the PST file. To recover from this error condition, you need to delete the PST file and recreate it with a smaller size first (i.e., with a smaller filename). To do this, follow these steps:1.) Press Windows+R on the keyboard to open the Run dialog box .2.) Type “regedit” and press Enter .3.) In the Registry Editor dialog box , navigate to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Outlook \ FileFormats .4.) Right-click on FileFormats , and select New > DWORD Value . Name this value “FileSize”, and give it a value of 0x0B00000 (i.e., zero bytes). If you don’t have access to an administrator account on your computer, install some form of user account control (UAC). Now right-click on FileSize , select New > DWORD Value , name it “FileSizeLow”, give its value a value of 0x0B00110 (i.e., 1 bytes), and set its data type as “short”. This will enable Outlook to read any larger files without an error message. Note: If you are using Windows 7 or Windows 8, changing this setting will also erase all other settings related to compatibility with Outlook 2007/2010/2013/2016 etc.). These settings will also be restored automatically upon restarting Outlook after clearing out some unnecessary junk from its cache partition (though only for certain versions). Note that if the inbox size is above 100 MB when you create a new folder in Outlook 2013 or later (or if there are more than 10 folders in an inbox), then none of these
