I already have a Direct domain but want to add another domain.
If you would like to add another Direct domain to your organization then you should complete a new registration. Each domain needs to be registered separately.
NOTE: Registration is not for adding users. If you are trying to add a “user” mailbox (user@) to your existing account then the Administrator for your account. If you do not know who the Administrator is for your account you can email helpdesk and we are glad to assist.
