Can I transfer all IMAP folders to Thunderbird at once?

If you are trying to import IMAP emails to Thunderbird, then use Yota IMAP Migrator which offers excellent features and accurate migration. You can also save emails into formats like PST, EML, HTML, or PDF. A free demo is available to migrate 10 emails from IMAP to Thunderbird.

I recommend using the MacSonik IMAP Backup Tool, you can easily back up emails from IMAP Server to different file formats like PST, PDF, MBOX, EML, EMLX, MSG, CSV, DOC, DOCX, etc. It removes duplicate emails based on To, From, Date, and Subject. Using this utility, you can migrate IMAP mailboxes to Office 365, Gmail, Exchange Server, IMAP, etc. It also helps to skip duplicate emails and free up the server space after creating a backup of IMAP emails. The demo version of this tool helps to convert 50 emails per folder. This tool can run smoothly on all major and minor versions of Mac OS.
