I know the security folks are going to tear into me for this, partly because I use the word Secure, and partly because it is not truly secure. Let me share with you some ideas on how you can install Exchange 2000 and AD and let your users connect from the Internet with their MAPI client as well as OWA.
Lotus Notes/Domino (or simply “Notes”) and Microsoft Exchange migrations have traditionally been painful processes. In nearly every migration, there is an amount of time where running both systems is required, especially in large scale deployments. In many cases, both systems remain indefinitely in the environment.
It is rarely wise to do something simply because you can. With Service Pack 2 of Exchange 2000, it is now possible to run Exchange 2000 and Microsoft Sharepoint Portal Server on the same box. I may argue against such a configuration in the name of network efficiency, but I am not completely one-sided in my opinions when I touch ever so cautiously—on the few special scenarios for which it may be a good idea after all.
With Exchange 5.5, this was simple because we had a service account. We simply logged in with the service account or used the credentials to gain access. This was most helpful when we were restoring a mailbox or otherwise capturing data in a lab or temporary restore server.
Those of you who have rebooted their connector servers or experienced a performance hit with message conversions already know what I’m talking about. Those considering a migration to Exchange from cc:mail or Lotus Notes in particular should pay close attention.
This document was prepared in order to detail the mechanics behind a Service Level Agreement between a fictitious Company ABC and an outsourcing vendor. Several specific requirements have been assumed and documented in this article. My goal was to product a template that other companies could use to begin work on their own SLA.

Exchange 2000 applications are much more reliable than those running on Exchange 5.5. Because of this new added stability, a great many companies are now looking to centralize the Exchange 2000 application servers within their company.
