I am facing an issue with a PST file that was previously used with my office email account. The file appears to be locked, and I am unable to open or access any of the data inside it. Since the email account is no longer active and I do not have access to the original Outlook profile, I am stuck with this PST file that refuses to open. I have already tried opening it on another system and in a new Outlook profile, but Outlook keeps saying the file is locked or being used by another program. Can anyone suggest a safe and reliable method to unlock this PST file and access the emails and other data inside it?
