I had the same issue with multiple PST files and wanted to combine them without losing anything. I used Stellar Merge Mailbox for Outlook, and it did a great job. The tool merged all my PST files into one unified file while keeping the folder structure and data intact. It also helped remove duplicate emails automatically. The process was straightforward and much safer than trying to merge manually. Definitely recommend it if you want an easy and reliable way to merge PST files.
