Exchange Server 2007 - Multiple Domains and Email Accounts for the Domains

Hello All;
Just installed Exchange Server 2007 Standard, on our 32 Win2k3.
For the default Domain that is created with the installation, I have successfully created multiple email accounts and test the local email delivery, and every works flawlessly.

Now, for External Domains.
I have successfully setup a NEW [Accepted Domain],
and have created the [E-mail Address Policy] for the domain.

My question is this:
When I go into [Recipient Configuration - Mailbox],
and I create a [New Mailbox]
I do not see the new Domain.

What else do I need to do, in order to create new email accounts for the new Domain?

Thanks All
LVL 31

If you are talking about real "External Relay Domains" then you don't get to setup email addresses for that domain.  They need to be setup on the hosting server.  By configuring a relay domain, you are saying, "No, I don't host this email domain, but I will accept email for it and forward it on to the correct handlers."

Now if you are talking about "remote domains", again, this does not allow you to set email accounts for said email domain.  It only allows you to control formatting options on outbound messages to the remote domain.

Are you hosting this domain, or is it hosted elsewhere?

When you create a new Accepted domain and add it to the Policy .... is that a new Policy or editied the default policy ?

1. Remember that its Priority has to be higher than the Default policy.
2. Did you create any filter fol the new policy how users will be filtered ?

I could not find anything from the link you provided, that will assist in in this issue.
Thanks anyway.

OK, I am learning as I go here, with this software, so please bare with me.

#1: On my Hosting Providers site, within my DNS Admin there:
have an A Record to points to this [IP Address].
#2: I have created the DNS Records from the Domain with the Static IP Address from our ISP.
#3: I have created the information within Exchange, for the Domain.
#4: The Priority is set to [1], and the Default Policy [Lowest]
#5: Filters (This is how i have it setup)
[Users with Exchange mailboxes]
[Recipient is in a Company]

Other than the above information, that is it.

So do you mean that its filters can see all the Recipients ?

Did you enable and apply ?

Wayne BarronAuthor, Web DeveloperAuthor Commented:
>>Did you enable and apply ?
Where would [Enable] be at?
Yes, it is [Applied = True]

>>So do you mean that its filters can see all the Recipients ?
No, it is: [The following specific types]
Manpreet SIngh KhatraSolutions Architect, Project LeadCommented:
When you created a user what filter did you specify and what if you right click and say apply or run the

Update-EmailAddressPolicy command for that policy and let it runa nd check the user.

Hey Rancy.
I really do not follow what you are stating in your post.
>>created a user

OK, before I get to far ahead of myself.
Let me ask this.

OK, I have been doing some research prior to choosing to go with Exchange, and I found out that a lot of ISP and Hosting companies use Exchange to host domain Emails for clients.

So, in the case of the Hosting companies, I assume they did as I did, and Added in a Domain for the Client, so, from here, what would they do in order to host the email accounts for the client?

This is what I am wanting to do.
The email server application that I am use to is IMail Server.
And with that particular server, I just add in a domain, then add users to that domain.
However, Exchange does not seem to be like this, and I need it to work like this.

So my question is:
Can I add in multiple domains.
Then create Users for that domain within Exchange itself.
And if so, then Please HOW!!!

I think that should cover it.
If I cannot get Exchange to work the way I need it to work, then I guess I will have to go back to using Imail Server, of which I prefer Exchange if possible.

Heading out for the rest of the day, will be back in this evening, and hopefully with some advice to be used to resolve this issue.
Jon BrelieConnect With a Mentor System ArchitectCommented:
No problem.  You add the domain as an accepted domain.  If you want users to get email addresses created automatically, you create an email address policy for each domain.  As you stated, you filter on 'exchange recipients' and 'User is in a company'.  Then you define your email format.  This will apply to all users with the company attribute set.  However, you must also have each user configured to automatically update email addresses based on policy.  Check to see that your users have this enabled by checking the "Email Addresses" tab of the user properties within EMC.  Make sure you have a check next to "Automatically update e-mail addresses based on e-mail address policy"

That should do it.

You are mixing up the EMAIL domain and the WINDOWS domain and UPN.

During the new user configuration, the "Domain" you are seeing in the wizard is for WINDOWS login, nothing to do with the email addressTheHe email address is configured by email address policy later on.

If you want the email address and the username to match, then you need to add the domain as an additional UPN, which is an AD function. However even if you change the UPN during the setup of the user to something else, it doesn't change the email address the user gets - that is done by email address policy.

Wayne BarronAuthor, Web DeveloperAuthor Commented:
Your information seems very solid, however, I am completely lost in translation.

Yes, I know that the first domain that is created is the Server Domain.
UPN = I have been checking in on it, to see what it is, and what it does
And it seems that it is something that is needed in this issue.

So, I ask that someone please instruct in Steps how to perform what I need to do
In order to add email addresses.
Wayne BarronAuthor, Web DeveloperAuthor Commented:
After doing research on the UPN, I do not think that its what I am needing.
It seems that the UPN is for Logon security into the domain.

I just got finished going through a lot of the following page(s)

Very good article, on how to do a LOT within Exchange itself.
However, I am looking at all this that needs to be done, and am thinking right now, that using Exchange may be an overkill for our company.
Not to say that it may not be something that we will need later on in the future.

I think that we might have to go back to using what we know for the time being at least.
And that is the IMail Server.

I would like to thank everyone that came in here to assist in this issue, however, we are getting in the new Router tomorrow, and by Monday, we need to have a live working Email Server, for 5 domains, and up to 10 Sub-Domains, with users on them, sending and receiving email.

I know that Exchange will do this, and more, however, I just do not have the time right now to invest in getting this Mail Server up and running like I need it to be.

Thank you all
I am going to award everyone points that contributed to this thread with actual helpful information, that helped me to learn that much more of the system.

Now, time to reinstall Imail, and uninstall Exchange.
Wayne BarronAuthor, Web DeveloperAuthor Commented:
Thanks everyone
Wayne BarronAuthor, Web DeveloperAuthor Commented:
Hello everyone.
It is called: Exchange Hosted Mode
Which will allow you to host multiple domains, just like an ISP or Web Hosting provider.

This is what I was needing, and just happened to have just found the information.
I am going to look in on doing this, and hopefully everything will work out OK.
