Rated 4 out of 5 stars

This addon mostly works and does most of the heavy lifting involved when integrating Thunderbird with Office 365. However, despite many attempts, I cannot perform address lookups for my organization.

Plus, Beonex support does not seem to respond to support requests. However, it's still a fairly good add-on

This review is for a previous version of the add-on (0.7.7).
