I installed and reinstalled QuickBooks Pro 2019 and the email problem still exists in one of my companies and email still works in the other company. When I try and do your second solution...Contact Us isn't an option. The amount of time I have spent on this, it would have been cheaper to buy a new version of the program, which in the end I feel that's all the company wants me to do anyway. I have 2 small businesses where every penny counts and I can't really afford it but not being able to send invoices and get paid isn't an option either.

SO FRUSTRATED!!!!
