I'm assuming you're asking how to change your email address on a specific online platform or service. Could you please specify which platform or service you're using (e.g. Outlook, Gmail, Facebook, etc.)? That way, I can provide you with more accurate and relevant instructions.

In general, here are the steps to change your email address on a platform or service:

1. Log in to your account on the platform or service.
2. Go to your account settings or profile page.
3. Look for an option to edit or update your email address.
4. Enter your new email address in the required field.
5. Confirm your changes by clicking on a "Save" or "Update" button.

Please note that some platforms or services may have additional steps or requirements, such as verifying your new email address or updating your password.
