Trying to use Thunderbird in the corporate world was frustrating - but just for two reasons:
1) Accepted recurring calendar events that started in the past would pop up reminders that could not be dismissed (they would just pop up again immediately).
2) Thunderbird had problems embedding meeting links in the calendar event (especially, if the meeting was rescheduled), so you'd have to go find the original meeting invite email.
For those two reasons, I ended up installing Outlook to handle corporate stuff while TB took care of everything else.
I see from the release notes that these two issues have been worked on so I'll have to see what happens when I re-add my corporate account again; it will be great if the calendar is fixed.
I found that #1 occurred for all events as they rolled forwards, so, for example, if the event occurred every Wednesday and the first one was in January, I will get a popup for today's meeting, but I will not be able to dismiss it on TB - I'd have to use my phone to delete the current event once it had passed to stop the nagging.
