I had an old OST file that I couldn't open because the original Outlook profile was no longer available. I only needed a few important emails in MSG format to share with a colleague. After trying a couple of methods without success, I used this tool. It loaded the OST file without much effort, and I was able to export the required emails with their attachments. The MSG files opened correctly in Outlook, so it solved the problem I was facing.
