Import Outlook PST Files into Thunderbird

Windows/Linux (Thunderbird): Import Outlook's PST files and choose which email folders to bring into Thunderbird with PST Import, a free extension for the open-source, cross-platform email manager Thunderbird. While Thunderbird can import certain messages and settings from an existing Outlook installation, the PST Import add-on lets you set up email on Linux systems, and gives Thunderbird users the ability to pull specific email folders from a stand-alone PST file. The program was coded in France and one user review noted a dialog pop-up in French language, but the instructions should be fairly straightforward, regardless. PST Import is a free download and is listed as working with Windows and Linux versions of Thunderbird
