Mozilla Thunderbird is an open-source email client application but it does not provide PST files for Outlook. So in this situation, Mozilla Thunderbird to Outlook Converter tool of MailsDaddy is the best option for the users.

This GUI application is designed to transfer bulk mailboxes from Thunderbird to Outlook PST format without any technical hassle. It allows the user to manage all folders, subfolders, inline images, attachments, header, and other properties. You can use the application on Thunderbird MBOX and Maildir files at the same time and migrate both data from Thunderbird to Outlook.
