Use the user registration tool in the Domino Administrator client to create a generic user account. As the user's person document must contain the Domino domain name, the user must be a Lotus Notes mail user. It is advisable to give the user a sensible generic name, such as Enterprise Vault Domino Archiving.
You can prefix the last name with the special character '&' to ensure that the user is only displayed at the end of the address list; for example, Enterprise Vault Domino &Archiving/organization.
