Review for TbSync by Ahnoold
Rated 5 out of 5 stars
This review is for version 3.0.1 on Thunderbird 91.4.1. For me, this add-on (combined with with Provider for Exchange ActiveSync) are absolutely necessary for connecting Thunderbird with my work's Office 365 account's calendars and tasks list.
This review is for a previous version of the add-on (3.0.1).To create your own collections, you must have a Mozilla Add-ons account.
