Yes true, I have also removed the password from some of the password-protected PST files with the help of a PST password remover. Recently, I have just lost the database sheet where I saved the password. Then, one of my colleagues recommended the MCT Outlook PST Password Remover to unlock the password-protected PST files. This utility helped me to perform this action. Additionally, it kept my file data in its original hierarchy.
In case you want to analyze the performance of this advanced utility then you can also try its free version. It will remove and change the password of encrypted PST files of size up to 10 MB.
