Como faço pra para o icone ficar na barra de ferramentas?

Hi there,
It doesn't work for me. I use Outlook Office 365, not OWA, but I have owa in my url, as required by the add-on. Why doesn't it work then? Is it a matter of language (French in my case)?
Please help, this add-on would be really useful for me!
Thanks

It works, but it's REALLY buggy. 'Reminder snooze time' is in centiseconds (??? what ???), setting this field to 0 does NOT disable it (Also this crashes FF), I receive multiple alerts for the same emails, Cannot filter by email folders, etc...
Regardless, it works, so I'm happy, but this Needs Improvement.
