I'd prefer the eSoftTools PST to MBOX Converter Software if you're looking for detailed details on "How do I export Emails from Outlook to MBOX." It has a very easy and smooth performance. It shows a live preview of the PST file elements before starting the conversion process. Help is available 24 hours a day, seven days a week. All buyers have access to the free demo version, which converts 25 email items per folder.
