One of my old Outlook OST files had to be moved to a Zimbra server, and I wasn't sure how to handle it because Outlook wasn't available on that system. After trying Softaken OST to TGZ Converter, the mailbox was exported without much trouble. The folders stayed organized, and even the attachments were there after importing the TGZ file into Zimbra. It saved me from doing everything manually, and the whole process was smoother than I expected.
