This add-on is fantastic and should really be part of the default Thunderbird program. It is very straight forward to use and required very little input to setup with my mailbox.org account.

All of my calendars, contacts and tasks are synced with my provider. Not that it affects me, but there are also other addons for different providers that work with TbSync.
