When adding a new Administrator to the JumpCloud Portal, the action results in an error "The email admin@yourdomain has already been registered."
The email address has already been used to register an administrator account in an organization within JumpCloud, not necessarily the organization displaying the notification.
Access to the organization containing the account is necessary. Log in as an administrator with the account that has already been registered. If the password is unknown, follow the password reset workflow
To immediately have the ability to add the account to another organization, change the email address of the account where it currently resides or delete it entirely
If the organization where it currently resides was created in error or is otherwise no longer used, contact us to process the organization for removal.
