How to Troubleshoot a cPanel Account That Cannot Create New Email Addresses

Mailbox creation can fail because of account quota, domain configuration, permissions, or an administrative policy.

Checks to make

Capture the panel error, review account and email quotas, confirm the domain is assigned to the account, and check whether the requested address already exists as an alias or forwarder. Avoid deleting mailboxes to free capacity without confirming retention needs.
