No, cPanel does not have a feature to rename an email address. The only option is to create a new email account and delete the old one. This works fine if there’s no email in the older mailbox, but it can be a disaster if you delete it without first transferring your emails. So, the right way is to first log in to the mailbox you want to rename, check if any emails need to be migrated, and only delete it if all looks fine.
Good to Know: Migrating emails from one mailbox to another can be tedious. It’s not really a DIY task, so have your IT team look into it—or get in touch with our support to help you rename your mailbox.
