Lately I deleted email account used for zoom. The problem came when I need to manage zoom account using zoom web portal. They sent a verification code to my zoom email which is it didn’t exist.
I create zoom email account and did verification code resend and then the code didn’t come :D. I contact zoom support and they ask host key , how I knew the host key if I can’t login on their web portal.
Seem the block my email account block because they detect my email account didn’t exist. The solution, I login to my email account and send an email to email@example.com tell that I can’t receive verification code. It’s may trigger zoom to release their block to my email account.
