Win 2000 server and exchange 5.5

what the articles are referring to is Active Directory Users and Computers located in the Administrative Tools on your W2K Server domain controller. you add new users to your domain via Active Directory Users and Computers and in doing so create a mail box in exchange. There are many articles dealing with Exchange 5.5 in an Active Directory environment, notably problems with the Active Directory connector failing to associate a mailbox to an object [abit user]. please see http://support.microsoft.com and search the knowledge base for Microsoft Exchange 5.5 and use the key word Active Directory in the search string.

If you haven't setup active directory, you setup your users via Computer Management in Administrative Tools (local Users and Groups). As Exchange 5.5 doesn't have Active Directory funtionality this shouldn't be a problem.
