Microsoft Outlook allows users to secure their PST files by protecting them with a password. If a PST file in your Outlook profile is password-protected, a dialog box will appear on your screen that will ask you to type the password for the PST file if you try to open it.
If you have protected the PST file with a password, you can enter the correct string of password to access the file.
But if you are not the owner of the file or if you have lost or forgotten the password, you cannot access it anymore. Without entering the correct password, a password-protected PST file cannot be opened or accessed in MS Outlook.
This might be quite frustrating for an Outlook user. What can be done in such a situation? If the original password of the PST file has been lost or forgotten or if you want to access a password-protected PST file without having the original password, you can try a manual but an effective solution here.
I do not know whether you remember or not that Microsoft has designed a utility, known as pst19upg.exe. This utility is primarily designed to upgrade the older version of PST files, i.e. ANSI PST files. Its main function is to make the ANSI PST files upgraded, so that they can easily be accessed or supported by the later versions of MS Outlook. There is a “so-called” demerit of this utility that it removes the password from the password-protected PST files while performing the upgrading process. This could be a side-effect of it, but it can be helpful in removing the password from the PST files. Besides pst19upg.exe, you also need scanpst.exe.
You need to download pst19upg.exe manually. But scanpst.exe can easily be found on your system. Once you are ready with the utilities, you need to follow the steps given below:
- If MS Outlook is opened on your system, close it. Before performing any manual solution, you need to take backup of the original PST file or you can create a duplicate copy of the file.
- Once the backup job is done, run scanpst.exe. Make sure you use duplicate copy instead of the original file.
- Open the Command Prompt by clicking on Start menu > Run or Win+R button. Now type the file path to pst19upg and your PST file name, for e.g. pst19upg.exe -x filename.pst and hit enter.
The command line will be shown like this:
“C:\My Documents\pst19upg.exe” -x outlook.pst
By using this action, a copy of the PST file will be created and called “filename.psx”.
- Once you are done, you need to rename the file.
- Type pst19upg.exe -i filename.psx at the command prompt and hit enter.
- A new password-free PST file will be created from the psx file.
- Now run scanpst.exe with this new PST file and click on Repair, if prompted.
- You can open the file in MS Outlook.
As the pst19upg.exe utility is used to upgrade the older versions of PST files, this means it cannot work with the files which are created in newer versions of Outlook, such as: 2003, 2007, 2010 and Outlook 2013. Or sometimes this utility may not work. In such situation, you need to use a third-party PST Password Recovery tool. Try SysInfoTools PST Password Recovery tool that works with both ANSI as well as Unicode PST files. It will recover the original password of the PST file by using which you can re-access your PST files.
