Finally Microsoft has came out with Exchange server that could
support multiple organizations without the need of HMC or manually
making changes in ADSIEDIT or Active Directory. I have actually not
used HMC before but found that trying to segregate address list and
GALs manually in Exchange 2007 was a pain.

What is not available

• Exchange Management Console

• Public Folders

• Unified Messaging Server role (can install on different machine)

• GalSync

• Federation

• Business-to-Business features such as cross-premises message
  tracking and calendar sharing

• IRM

• Outlook 2003 support

• Edge Transport Server role

• Same forest upgrade from Exchange 2007

• Resource forest

• Parent-child domains

• Discontiguous namespace

• Disjoint namespace

I know that most get upset at the Exchange Management Console not
being available anymore but I find that the shell commands are really
simple and easy (especially with the help of Google and Microsoft
help pages).

You can still easily create new users/mailboxes using the Exchange
Console Panel through OWA. We will get to that in a little bit.

Setting up your Lab environment

Note: You must set this up in a domain that Exchange has not been
installed in before

For this tutorial I am going to install the Exchange server on top of
the DC. Now this is a *supported* configuration with Microsoft, but
it is not one they recommend. What I would do for smaller
environments is setup two DC’s, two CAS servers (with hub transport
roles ontop), and two mailbox servers in a DAG group.

*Update*

You should check out the Exchange system requirements before
continuing: http://technet.microsoft.com/en-
us/library/aa996719.aspx. You must have your Active Directory forest
level at 2008 or higher

First thing would be to install the prerequisites:

1. Open command prompt

2. Browse to the SCRIPTS directory

3. Type: servermanagercmd -ip EXCHANGE_ALL.xml

    

[Please note that the picture shows EXCHANGE-TYPICAL when it should
show EXCHANGE-ALL]

After you install that and reboot you will need to install the other
prerequisites:

1. Office 2010 Filter Pack x64

2. KB977020

3. KB979744

4. KB982867

5. KB983440

You can download them here if you would like: Exchange 2010 SP1
Install Files

Now open command prompt and type:

setup.com /m:install /roles:m,ht,ca /hosting /on:LabEx2010

It will begin preparing active directory and going through its checks
and installation

That is it! We are now done installing. So reboot and open the
Exchange Shell. For step 2 we are going to go over creating service
plans and creating new organizations!
