Rated 1 out of 5 stars

Been using it for a few months now, was hoping to get Exchange functionality into Thunderbird so that I didn't have to use OWA (I use Linux).

Plus points:
It receives mail.
It gets my contacts.

Negative points:
Makes Thunderbird run like a dog.
No access to calendars.
Does something horrible with meeting requests.
Have to use OWA anyway.

Got a pop-up telling me that I'd have to pay to continue using it. I would pay if it was useful, but it's worse than useless, so I'll be getting rid of it.

This review is for a previous version of the add-on (23.1).
