Question

Not all invitees are receiving the invite and it is not in their spam. One in spam couldn't move it to in box

Answer 1

some mail providers see invites as spam and totally block them. if you have a closed membership group, you're in a bind other than sending the invites to a different mail provider the person may have.

if it's not a closed group, log onto the group and copy the URL fro the browser, paste it to an e-mail and send it that way- the person then goes to the group and click the large blue tab top right Join This Group
