I want to sync my Thunderbird Lightning calendar on my office laptop with my Samsung S III calendar. How can I do that?
Have you considered using the Google calendar?
As far as I know you can sync the Samsung S III and the Thunderbird Lightning calendar with the Google calendar.
As you don't specify, I assume your office laptop is running Windows. In this case you might want to take a look at the MyPhoneExplorer Client App for your SGS, and its desktop pendant for your laptop. As far as I know (I'm not a Windows user), this should be the best and complete solution -- not only caring for your calendar with Thunderbird and others, but doing a lot more useful things to manage your device.
