Thunderbird is great until you receive Teams invites. It removes/hides the links in the calendar entry so you need to keep the email in order to be able to click on the meeting link.
Weird, I join teams meetings every wednesday from Thunderbird. I can either use the Today/Events Pane (f11 to toggle), the calendar tab (Alt+3), or find the email. To find the link in calendar view or from the events pane, all you have to do is double click on the event. The link, Meedting ID, passcode are all in the description box.
Maybe it was a previous issue that they fixed, but, for me, it's been working for months without a hitch.
