Calendar Shared

Hi All,

I''m a new user of this tool, I'm interesting on One calendar for several users but I don't understand how this
option works under configuration section, I mean, I've allowed several email accounts to have access to edit/add events
on this calendar but it seems doesn't work by this way.

Any idea?

What Am I doing wrong ?

Thanks in advanced,
Regards,
