Thunderbird supports MBOX and Maildir file formats that cannot import into Microsoft Outlook. The software helps the technical and non-technical users to import single or multiple Thunderbird mailboxes to Outlook PST format. If you want to migrate data from Thunderbird to EML, MSG, HTML etc. then you can also use this software.
The free demo version of the software converts 20 emails from each mailbox. Get more detail: Migrate Thunderbird to Outlook
