You switched to Outlook, but years of mail are still sitting in Thunderbird as .mbox files that Outlook can't open. Retyping, forwarding or dragging messages one by one isn't realistic. Move Thunderbird Emails to Outlook, sold as the Thunderbird Converter, is built for this job. It turns Thunderbird mail into PST files that Outlook reads.

Key features
Get Thunderbird mail into a PST file Outlook can use
You pick your Thunderbird mail files, choose PST as the saving option and click Convert. The vendor describes the whole job as four steps.
Keep attachments, formatting and read status
The converter carries over attachments, formatting, read/unread status and message details such as to, cc, bcc, date and subject.
Convert many mailboxes in one run with batch mode
Batch conversion lets you process several Thunderbird mail files together instead of repeating the steps for each.
Save as EML or MBOX when PST isn't what you need
Besides PST, the tool can save Thunderbird email in EML and MBOX formats.
Who it's for
It suits you if you're leaving Thunderbird for Outlook and have a large mail archive to bring along. It also suits you if you want to avoid manual export and import. The vendor says even a novice can run the conversion.
