Attendees to google calendar not work

[telejet]

We use Thunderbird, lightning and Google provider 0.4 to sync with
google apps for our domain

And the problem we have is: at the time to sent an invitation in
lightning, the option send invitation to assistents is deactivated. We
have enabled the option SendEventnotifications in the advanced editor
but still not working. It only works when choose local calendar but
not with the google calendar.

Is there any solution?

Thank you
