Update Login Email
If you need to update your login email address, follow the steps below. In some cases, only administrators will be able to update your login email.
To edit your own login email address
Login email addresses (user ID) cannot be edited by anyone. If you need a new account login email (user ID), a new account will need to be created for you by an administrator.
To edit a user's login email address as an administrator
Even as an administrator, you cannot edit another user's email address (user ID). If a user needs a new email address, a new account must be created for them.
Refer to Activate or Deactivate a User Account for additional information.
