    I am trying to migrate my email data from MBOX files and Thunderbird to Outlook PST format, but I am concerned about losing attachments during the process. I have important files embedded in emails. Can anyone suggest a reliable method or tool that ensures complete data integrity, including attachments, formatting, and folder structure during the conversion?
