,I have a godaddy instance of O365, and when I share with someone outside of my domain - the don't get the share link and it doesn't sync.
I have tried from a microsoft instance (i.e. not a godaddy one) and it works fine, so the issue appears to be with the godaddy settings...
We are aware of this limitation and this is something that Microsoft has to fix. We are waiting for them to fix this so that GoDaddy Office 365 customers can support this.
