If you want to back up Thunderbird Mail, it's easy. You can export individual messages and folders or your entire Thunderbird profile as a backup. Read on to learn how.

Things You Should Know

  • To export Thunderbird mail, select the messages you want to export, right-click or control-click the selection, click "Save as," then choose a folder.
  • To export your profile (all mail, calendar, and settings), go to ☰ > Tools > Export > Export, select a folder, then click "Save."
  • Exporting email messages saves them as EML files you can import into other mail apps. Exporting your profile backs up all data in a Thunderbird-only format.
