I am very interested in Hosted services especially Hosted Exchange. As a small system integrator company I have several customers who would like to get rid of the Exchange from their offices and let me maintain their mailboxes. So I would like to ask experts
a few things before I start.
Because I need to test the solution before I will implement it at my customers, first I would like to ask you a simple question. Actually the subject of this post is this question. Well, is it possible at all to establish such an environment on single server
connected to the Internet? I will focus on Exchange mostly.
I have already moved bit forward and rent a place in Data Center, purchased a server, put it there, and already installed Windows 2003 and Exchange 2003 with all updates on it. I have configured it for testing and it is working. What would be the next step,
if this is possible at all to keep it on one server?
I will appreciate any help

You can do such with Virtual Server. But then you get 32-bit. 32-bit Exchange isn't for production. Only for test-purpose. There is a unofficial/unsupported "consolidated" HMC4 solution in this forum, with the least number of servers you'll need.

Mike is talking about Exchange 2003.[;)]
It is possible, but complicated. You can go without solution at all (MPS and all this resource management stuff seems to be useless for your scenario). The best thing about solution is how it separates organizations inside AD/Exchange. You can do the same
manually on the single server, or you can script it. At some point of time, Microsoft had a KB article with manual step-by-step instructions of how to separate multiple organizations inside the same AD/Exchange 2000 environment. Unfortunately, I can't find
this article any more [:'(], so I don't have a good reference for you about how solution works. BTW, you can install HMC in virtual environment and revers engineer it. [;)]
Couple links, that probably will help you to understand how solution works:

What did you mean by, 'You can do such with Virtual Servrer. But then you get 32-bit. 32-bit Exchange isn't for production.' ???
I'm sure VMware's ESX 3.0.1/3.0.2 can run 64bit virtual machines?

The solution is not supported on virtual servers. Moreover, if you want multiple customers sharing the platform, the load and storage requirement will not allow you to use a single server. HMC 4 includes servers in 64 bits and others in 32 bits. However,
you can have some roles shared on the same servers, but it will really depend on the requirements.
For the exchange version, only the 64 bits is supported, the 32 bits can be used for test purpose, but that's all. Using virtualization for exchange mailbox server would not be a good idea, as the exchange 2007 version is leveraging more memory per user
in order to decrease the disk IOPS requirements.
To test the solution in a lab before deploying the production environment, you can definitely use Virtualization; I would add that I recommended you to have a lab environment in order to perform tests and hotfix updates before the production environment.

BTW, VMWare can support 64-bit guest OS. this is for HMC4.0
For HMC3.5, it's possible deploying the solution on 1 server, as mentioned, it's not so easy.
For test purpose, you can start some VM machines on your server, then go to deploy the solution.

Thank you all for answers. Dimitri I will appreciate it if you find those articles you mentioned about Exchange.
We have finally succeed with a separation tasks on the Exchange. Now different domains and organizations do not see each other, every of them can use Outlook through RPC over HTTP, OWA and mobile access, and GAL (global address list) contains
only members of particular organization (LDAP filter in the Recipient Policies helped).
Do you mind if I continue posting question regarding my problems as far as they happen on this forum (maybe in new threads)?
Thanks in advance for any help (donations like extra large memory to ML370 are also welcome :-)

The document Dimitri mentioned is no longer available on Microsoft resources. However, you can deploy Hosted Exchange in a lab in order to look at how MPS does the isolation (Creating a few companies and users and look at the permissions etc.)
Please be aware that deviating from the solution might remove the supportability. Contact your Microsoft TAM for more information. Make sure you always have enough backups, including OS image, to restart after an issue or disaster.
You can indeed post new questions on the forums; the community is here to help. Please use a new thread for each different question.

Dimitri I will appreciate it if you find those articles you mentioned about Exchange.
Samuel is right - this document is unavailable anymore. One of the keywords in document was
msExchQueryBaseDN. If you run search for this on support.microsoft.com, you will have 4 results and non of them is a a desired one. [:'(]

More than 4Gb of RAM for Exchange 2003 is useless.
FYI. My name is Dmitri, not Dimitri. [;)]

Thank you Dmitri!
Regarding the memory - I do not have even 1GB, so you have to admit that it is not enough for Exchange server. (but works [:D] for testing)
I think I will take Samuel's advice and install the environment on my laptop (also need more RAM), on virtual machines and see how does this work.
By the way, what is better solution VMWare or Microsoft Virtual Machine for this kind of testing?
Aug 17, 2007 09:25 AM|DmitriG|LINK
Personally, I prefer VMWare. MS Virtual PC is not scalable enough for full HMC deployment. MS Virtual Server doesn't support 64-bit guests and has less intuitive UI, IMHO.
But MS products are free, and, if you are going to play with HMC 3.5/Exchange 2003, it will satisfy your basic needs.
