Naming Conventions

You must provide names for directory objects when you install and configure Microsoft Exchange Server. Carefully planned naming conventions make it easy for you to add sites, connectors, and other directory objects. You should choose names for your sites and servers that won't be affected by organizational changes. The following table lists the naming conventions used by Ferguson and Bardell:

Element name Naming convention
Organization Company name; for example, Ferguson & Bardell.
Sites Geographical location; for example, NAmerica-W.
Servers Geographical location; for example, SanFrancisco01.
Mailboxes First and last names; for example, Maria Black.
E-mail alias Letters of the first and last name; for example, mariabl.

Every object in the organization has a display name and a directory name. You can change the display name of an object, but the organization, site, and server directory names can't be changed.

By default, the directory name is used to generate e-mail addresses. The Setup program maps the directory name elements, such as organization and site name, to the e-mail addresses, according to the naming conventions for any given system. For example, the Internet address for a user called Maria Black is

Directory Names
All directory objects are uniquely identified by a distinguished name (DN), which includes the full name, organization name, and site name. For example, the distinguished name for Maria Black's mailbox (MariaBl) is:
where: o (organization) indicates the organization name, ou (organizational unit) indicates the site name, cn (common name) indicates the Recipients container, and cn (common name) indicates the e-mail alias.
