Theodorerowan01 I recommend the **Softaken MSG Converter, it made my recent migration project so much easier. I had to convert a huge collection of Outlook MSG files for a client, and this tool handled it effortlessly. You can import individual files or entire folders, choose TGZ as the output format, and it does the rest—without compromising any data. It preserves attachments, metadata like To, CC, and Subject, and even maintains the original folder structure, which is a big help for organization. It runs smoothly on any Windows machine, works with all versions of Outlook, and doesn’t even need Outlook installed. If you need a quick, secure, and dependable way to convert MSG to TGZ for Zimbra, this tool won’t let you down.
