Not sure what you mean... You cannot have Calendars without Lightning - it is what provides the calendar functionality. > Beyond the value of having the calendar/task lists in a separate > window using Lightning, it seems the problem above is ls slightly > alleviated compared to not using Lightning. I used to think I preferred having the calendar in a separate window, but resigned myself to having it in a tab when the update that changed that happened. Now, I prefer it in a tab. I don't think that preference is a good enough reason to stick with an unsupported version of Thunderbird, but that is up to you. > I have ca 65 calendars/task lists How many calendars, and how many task lists? Either way, I hope you understand, that is a huge number, and the super vast majority of users do not have anywhere close to that many, the vast majority probably have less than 6. > and some of them also do not update - at all/never.

The problem is with Thunderbird. This is a known issue, and one that is not easily fixable, because it has to do with the underlying non-threaded code. > - Why is the e-mail functionality of TB blocked while calendars/task > lists are being updated? Because everything works on one thread, and the calendar code is not written to throttle itself when working. > - How can I investigate why/how some calendars/task lists are not > being updated? It is likely a bug related to the huge number of calendars you have, but one that is unlikely to be specifically addressed, but may be fixed if/when the underlying code is rewritten. -- users@sogo.nu https://inverse.ca/sogo/lists
