You can manage users using the storage server SMI, not the application server.
Local users are served from the same Messaging system, regardless of the location of their home telephony server. You use the User Management Web page to add, change, or delete a local user or an info mailbox.
Remote users are served by a voice mail domain that is different than the voice mail domain of the local users. You must regularly update the list of remote users on your system to keep the system functioning properly.
Both local and remote users are members of the same voice mail network within your organization. Typically, local and remote users exchange messages with each other regularly.
