When I send event invitations through Google Calendar, there is one person listed that does not receive the invitation. All others in the list receive it.
He is on gMail too and has checked his spam folder. Other emails from me he receives ok. Is there some other setting he needs to change to receive the invitations?
Best Answer
This is likely because of he has explicitly denied sending notifications about events to him.
