ADSI is a interface for accessing Active Directory, you can use it to access
Exchange information that is stored in Active Directory but you are usually
better of using CDOEXM which wrappers most of the ADSI functionality you
want and provides additional methods for managing Exchange objects.

WMI in a Interface for accessing Exchange management information, this can
include things like SMTP queue length, mailbox sizes and Server Status (eg
mailbox store mount status etc).

Sometimes these interfaces overlap but they are moslty unique in the
functionality they provide.At the end of the day there is no one interface
in Exchange that does everything you want to do so you may find yourself
using ADSI, WMI, CDOEX, CDOEXM,EXOLEDB or WebDAV. Which interface you use
depends on what you are trying to do.

You might want to have a read of the programming technologies page from the
Exchange SDK
