Internet directory services, also known as LDAP services, are used to find e-mail addresses that are not in your local Outlook contacts. Directory services search directories on other servers to look up names and other information that can then be viewed in Outlook. You can locate an LDAP server on the Internet, on your organization's intranet, or through another company that hosts an LDAP server.

Note

  • After you add the account, you can select the authentication method, if it is required.
  • To set LDAP search options after you add the account, in the Accounts dialog box, select Advanced.
