The other licensed user

We have 2 licensed users, but I have always hosted the meetings. I need the other licensed user to host a meeting. When there has been a problem connecting I sometimes have to respond to emails sent by Zoom to get it straightened out. If there is a problem while the other licensed user is hosting a meeting he will not have access to my email. What does he need to do when starting a meeting to be sure that emails will be sent to his email address if there is a problem? Thanks.
