The tool automated the whole process of saving my 15 year old Thunderbird profile data as PST and it was done in minutes. Kudos to the team, they really helped me out through the process.

It helps me skip the manual hassle of importing. I can directly save my Thunderbird data as PST in the Outlook Profile folder and that has no additional import steps like other tools.
