I really like this add-on and was fine until something between Thunderbird/Lightning and Google Calendar decided to take control over events that were originally created from my Outlook at work. Suddenly it (one or other) is sending and re-sending meeting invites updates and cancellations as if I was the organiser!!! This has cause huge confusion and upset amongst work colleagues and I've had to disable the Thunderbird calendar.
I doubt that it is actually the add-on that is causing the problem but something between T'bird, Google an Outlook events. Either way cant find a fix online and so have had to revert to using the default Mac calendar which ain;t brilliant but does not have this problem.

This review is for a previous version of the add-on (0.18).
