That's a temporary error (anything 4xx is), so GIO will retry sending the invitation.? I'm not sure what the time is between tries.? Some services use this to "graylist" email senders like GIO to limit the amount of mail they can send in a relatively short time.
If you get a 5xx error, that means that GIO has received a hard error.? With those, it won't try again.
