Rated 4 out of 5 stars

Very nice piece of add-on.
Thanks a lot for it.

The problem I often have is that I have to configure -> setup account a first time..
Then, indeed, it waits forever.

At that point, cancel, restart Thunderbird, go to the preference tab for this plugin, remove the (bad) config existing for owncloud and add again with the same infos and it works directly...

This review is for a previous version of the add-on (1.3).
