Rated 5 out of 5 stars

Works 100% with mailbox.org, the cheapeast, most secure all-in-one replacement for outlook. Synchronization was automatically configured for multiple contact groups, multiple calendars, and even my tasks list. I could not be more impressed with this add-on's support for mailbox.org.

This review is for a previous version of the add-on (2.6).
