A System Administrator needs to update their Salesforce login email address but wants to use a free email service such as Gmail or Yahoo. Salesforce Support is unable to process email changes to free or publicly available email domains.
For example, if your organization's sole System Administrator has left the company and you need to update their login email to regain access, the replacement email address must use a domain your organization owns and controls (for example, yourcompany.com), not a personal address such as gmail.com or yahoo.com.
Salesforce Support cannot update a System Administrator's email address to a free, publicly available email domain. The new email address must belong to a domain owned and controlled by your organization, as Salesforce is required to verify domain ownership for security purposes.
When requesting an email change for the sole System Administrator of your Salesforce org through Salesforce Support, the request must be made using a domain owned by your organization. This is necessary because Salesforce must verify ownership information for the new domain to ensure security. For security reasons, changes to free email addresses or domains not owned by the customer cannot be processed.
