I'm seeing the same behavior with...
TB 3.1.10
Lightning 1.0b2
lightning-exchange-provider .13
I'm using it with Rackspace hosted Exchange, and I've tried every variation mentioned. When I restart Thunderbird it always prompts for the login twice.
What's really interesting is that the calendar actually displays before the prompts do... so I don't even know if uses those credentials that it's asking for.
