Review for TbSync by Ob3ron
Rated 5 out of 5 stars
I was stuck with office 365 not showing up the calendar in thunderbird ( while email was working just fine ). Then I tried this add-on and BOOM, everything started working like a charm. Just what I was looking for, perfect.
This review is for a previous version of the add-on (4.7).To create your own collections, you must have a Mozilla Add-ons account.
