Rated 5 out of 5 stars

Just updated to Thundebird 60 and looked for an alternative for "Exchange Calendar" extension, that uses EWS but is not more compatibile with TB 60.

TbSync worked perfectly, and with my surprise was quicker to configure. Just go to menu > Edit > Syncronization Settings and input e-mail and password, autodiscovery feature just done the work.

This review is for a previous version of the add-on (0.7.16).
