No Access to Previous Email for Confirmation of Changes.

Hi @MPA! Welcome to the Zoom community, we're happy that you're here 😊

The best way to solve this issue since you cannot access your old email address is to choose another sign-in method to access your account and then follow the instructions in this article to access your Zoom profile and change the email address associated with your account: https://support.zoom.us/hc/en-us/articles/201362563-Changing-the-email-associated-with-your-account

If you are still unable to sign in, I would suggest contacting Zoom support here: https://support.zoom.us/hc/en-us/articles/201362003
