    Comments about Thunderbird as an Alternative to Microsoft Outlook
    Comment summary: Thunderbird is praised for being a strong open-source alternative to Microsoft Outlook, with numerous extensions enhancing its functionality. Users value its seamless compatibility across different Linux distributions and appreciate the built-in calendar, though some desire further improvements in calendar integration. Many find Thunderbird intuitive and easier to use than Outlook, though a minority consider its interface complicated. Security and customization are notable advantages.

    Despite its age, Thunderbird remains the most fully featured email client out there. Various add-ons can extend its functionality, it (now) has a built in calendar and, unlike Outlook, it's free, open source and respects your privacy.

    The interface is just impossible for many people to use.

    I remember when I first used Thunderbird, many years ago, as I'd rather have a single interface for productivity. But the interface through me off and I never got on with the editor. Coming back to it now, it's fresher and smoother. Absolutely love it. In my opinion this is the only true alternative to Outlook. Then there's the bonus of extensions to further enhance it. Though, I'd like to see further improvements to the calendar integration.

    It runs on Linux and you still have content if you are offline.

    I can just find everything instantly, Outlook I'm having to go to Chat GPT to research where the option is hidden!

    This would be the best alternative, except that it requires the Gnome desktop, so users of other desktop environments need to look elsewhere.
