Rated 5 out of 5 stars

Many thanks for the update - now it accepts personal Live accounts once more and I could get my Live e-mail to work again. I thought the extension was becoming only for corporate usage - but I guess it was an issue on Microsoft's side.
One more question: why do the extension starts twice sometimes when I open Thunderbird?

This review is for a previous version of the add-on (0.6.9.1). 

Thank you for the nice rating. Yes, this was a regression that Microsoft caused on their servers and we spent a lot of time investigating it and trying to find a workaround.
