I was unable to remember the password of an old PST file in which some important emails were saved. Tried many free tools, but they either did not work or were too complicated. Then I came across the
Outlook PST Password Recovery Tool. It removed the password in a few seconds without any hassle, and I could directly access the file in Outlook. Its interface is very simple and does not require any technical skills. If you also want to unlock your PST file, then definitely try it once.
