For both of you. On the surface you each have a similar issue, but that is not necessarily true. As a start we need to know what exact error messages you are seeing when you try to send. And I mean "exact" not a paraphrase please. The error message contains information of value in diagnosing the issue. And it would be better if Daveg14 started his own thread. If it turns out you have different issues with the same manifestation then having them discussed in the same thread makes life more difficult.
Superuser 18/19. Use Kudos to say thanks Tick an answer as "helpful" only when the problem is solved Please don't send me private messages unless I ask you to. I do not work for VM. The advice I give is based on my best understanding of VM policy and practice. You rely on it at your own risk.
