I am currently using Microsoft Outlook on my Windows system, and I have an old PST file that contains important emails, contacts, and calendar data. For security reasons, I want to change the PST file password. However, I am worried about possible data corruption because the file is quite large and contains critical business information. What are the safest techniques to change a PST password without causing file corruption or data loss? I would really appreciate suggestions for reliable methods or tools that work safely and are suitable for beginners as well.
