If you want to export Thunderbird emails to Outlook, you can use the SysInspire MBOX Converter Software, which allows you to move mail from Thunderbird mailboxes to Outlook 2019, 2016, 2013, 2010, 2007, and other versions. It helps you move several large Thunderbird files into Microsoft Outlook at the same time. Meta properties (to, cc, bcc, subject, and so on), folder structure (inbox, outbound, sent, deleted, and so on), and attachments are all cleverly maintained. You can test the form's viability for free by downloading the demo version. This tool's demo version allows you to export the first 10 emails from each mailbox.
