In those cases, you should look into synchronizing your calendar through a third-party platform, like Google’s services or something similar that Thunderbird can integrate with.Privacy Policy for Beonex GmbH and Owl This Privacy Policy informs you how Beonex GmbH ('we') uses data about you and is a legal agreement between you and Beonex GmbH. The fact that it works on multiple platforms is a nice bonus, although the lack of a mobile app can be a big downside to some users. But if you don’t care about that aspect specifically, it should provide you with everything you need for a smooth, fulfilling experience. It’s not a special application in its corner of the market, and it can definitely use some improvement on the interface side. Lightning Calendar gets the job done, and that’s about it. Just don’t expect anything special compared to the competition. That said, if you aren’t too pretentious about the visual presentation of your calendar application and don’t want any specialized features aimed at large organizations, you should be just fine with Lightning Calendar. While it’s not free, it does offer more features than Lightning Calendar, and in a nicer package. Microsoft Outlook (opens in new tab) is perhaps the most direct competitor to Thunderbird, and therefore Lightning Calendar.

Most issues are resolved quickly, and you get the benefit of having multiple pairs of eyes on your problems. You might be pleasantly surprised by the responsiveness and helpfulness of the community though. There isn’t really any dedicated support team to speak of, unless you’re involved with the program’s development, which is a different story anyway. Mozilla has prepared a large help base full of useful information, but if you can’t find an answer in there, you’ll have to post on the community forums. Lightning Calendar’s support is mostly community-based, much like the development of the application itself. You can find a number of articles and threads on Lightning Calendar on Mozilla Thunderbird's website (Image credit: Mozilla) Support
