Once a user account is created, you cannot change the email address for an existing account.
To change the email address for a user account, you need to create a new user account with the new email address and then transfer the license to the new account. For detailed instructions, refer to Transferring licenses.
Note
To change the email address for the Order Owner Account, you must 1) register a new user account on the Appeon website using the new email address, and 2) contact sales@appeon.com to transfer the credentials (Order Owner & Appeon Enterprise Account when applicable) and orders to the new Order Owner email address.
