Hosted Exchange 2010 Setup Guide – Part 1
Posted in Exchange Server | 13 Comments | 71,557 views | 28/08/2010 09:17

A few days ago, Exchange Server 2010 SP1 just released and it’s time to install a Hosted Exchange organization without HMC. Before SP1 installation, you should not install any Exchange Server on your current domain forest. If you have one, you should remove it or create a new forest for the Exchange Server 2010 SP1. What I will have in my environment:

* 2 x 1 Hub Transport Role
* 2 x 1 CAS + Mailbox Role

I don’t have enough resource to split CAS and Mailbox Role. If you don’t need a huge infrastructure, you can do same thing as me. Now I’m ready to install Exchange Server 2010 SP1.

Download Microsoft Exchange Server 2010 SP1 from here:

It’s an exe file. You should extract it first. For your information, for the Hosted Exchange infrastructure, you should install SP1 by command line. There is no option on GUI for Hosted Exchange.

I’m going to install one of my Hub Transport server called EXGW01. As the first step, install required features:

servermanagercmd /ip Exchange-All.xml

Set “NetTcpPortSharing” startup type as Automatic with Powershell:

Set-Service NetTcpPortSharing –startuptype Automatic

Also Exchange setup has to extend active directory scheme so you need to install:

ServerManagerCmd -i RSAT-ADDS

After required features installation, you should restart the server.

When restart is completed, install Office 2010 filter pack.

Now we are ready to go.
Open a command prompt windows (CMD) and type install command. /mode:install /role:HT,MT /organizationName:HostedExchange /hosting

Full list of Role codes:

HubTransport: HT
ClientAccess: CA
Mailbox: MB
EdgeTransport: ET
ManagementTools: MT

So Step 1 is below:

At the same time lets check schema status:

Do you see differences between Exchange Server 2010 and Hosted Exchange 2010? Yes, in the Hosted Exchange configuration, you see a new unit called ConfigurationUnits.

Btw, installation is going on well..

And finally, we finished our first server installation. Now we have a Hub Transport server.

I’ll do same thing to my second Hub Transport server. After installation, I’ll will make them load balanced servers. I’ll show how to load balanced them later.

Next, I’ll start setup of CAS and Mailbox Server. As I said, they will on the same server because I don’t have so many resources. Also as you know, much servers means much license prices. I use CMD again for the installation. But before the installation, install required updates.

You don’t need to reboot your server after updates.

If you don’t install required updates, Exchange setup fails.

Start installation: /mode:install /role:CA,MB,MT /organizationName:HostedExchange /hosting

If you installed all required features, then setup would finish without errors.

After setup completed, you have to reboot your server.
Now go to second server and do same processes to other CAS + Mailbox Server.
If you finish installation of second server, we can continue with configuration of our Hosted Exchange environment.

I’ll post configuration of Hosted Exchange 2010 at the second part. We completed our Part 1.

Please continue with Part 2:

Thanks for this great guide. I have been following some of the steps but i have CAS/HUB and MBX server setup instead of CAS/MBX and HUB.

My question is, why do you have to install these updates? All my servers is fully updated and patched so i guess they should already be installed? Why are they needed?

Where does this file come from: Exchange-All.xml ?


April 12th, 2011

In the Exchange Installation media, there is a directory called “Scripts”. Exchange-All.xml should be there.

Great article. I have been playing with Website Panel and with your article this helps complete the entire hosting for Exchange. I still wish I had a GUI interface, but powershell will work for now.

None of the hotfixes you listed are applicable to my Windows Server 2008 Standard R2 install (and I did try them) and when I try to run the 2nd install cmd “ /mode:install /role:CA,MB,MT /organizationName:HostedExchange /hosting” it fails but doesn’t give me a reason or KB number.

Any suggestions?

Could be a different issue. Note that the MT role gets installed from the first command when you install the HT so no need to include in the second command. Remove the MT from yours and see if it goes through.

I do trust all the ideas you’ve offered for your post. They’re really convincing and can definitely work. Nonetheless, the posts are very brief for newbies. May you please extend them a bit from subsequent time? Thank you for the post.

this also needs to be done before installing

What version of Microsoft Exchange 2010 is required to provide hosted exchange on a large scale? Are there any limitations with lower versions that would cause growth problems. For example, I am aware that the standard version of Exchange 2003 had a 75GB limit.
