E2E Encryption Emails

Hello,

I am developing a Zoom app where I need to collect and analyze user emails. However, I’m encountering an issue: the emails I receive through the API appear to be encrypted.

I have a few questions regarding this:

1. Is it possible to disable end-to-end encryption (E2EE) for default Zoom email addresses (zmail addresses), or is this always enforced?
2. From my understanding, E2EE can only be disabled for one custom domain per account—is this correct?
3. I have added and verified a custom domain under Account Management > Account Profile > Associated Domains. However, I am struggling to associate user emails from this domain in a way that allows me to disable E2EE. Am I missing a step here?
4. The documentation frequently mentions "Mail/Calendar Management," but I do not see this option in my account. Is this something that requires additional permissions or a specific account type?

I have a zoom workspace business account. Any guidance or clarification on enabling access to unencrypted emails or managing email domains would be greatly appreciated!

Thank you.
