Problem with exchange server, changing domain


HI,
  I have got windows small business server 2003.  I have four client pc's, we have all the same email address.

The address is domain eircom.net.  I have set up exchange to handle mail.  Issue is it is not working correctly, it is not retriving mail correctly also if change settings it wont send.

I am wondering is there an issue if the server domain is set up different to the mail domain.  When the server was being built the domain was set up as ifp.local, however we dont own a internet domain for our company so we use eircom.net for our mail.  Does this mean we have to to change our server name to be eircom.net instead on ifp.local or does it matter?  Is there any way of changing the domain rather than reinstalling server 2003.


Thanks
Stephen.

Hello,
You don't need to change your AD domain name. FYI AD domain names are not meant to be changed (you'll need the rendom tool to do it, so it's better to leave the AD name untouched !!!)

Just check the following :

Exchange System Manager/Recipients/Recipients Policies
Double-click on the "default policy" and select "E-mail addresses (Policy)
In the "Generation rules" list, check that the Primary SMTP address is set to "@eircom.net"

Also check that the "Address space" is set to "eircom.net" in Exchange System Manager/Connectors/SmallBusiness SMTP Connector.

It should work fine and you could have multiple SMTP domains on 1 SBS 2003 Server.

you have misconception about exchange hosting for multiple domains. Exchange server can host mails for multiple domains. Just read the links below, and you will know how to achieve your goal.

Hi,
Sorry about delay in replying.  I was away for bit..

Since i added this post exchange has been reinstalled.
So i am efectivly starting from scratch with exchange.
As I am starting setting up excahnge from scratch is there a different or better way of implemnenting exchange to pop and smtp may mail as mentioned above.

My ad domain is ifp.local, my email domain is eircom.net which is an internet mail account. This mail is hosted by eircom and I presently pop/smtp it using outllok. I want exchange to do this and send it out to my client pc's.  
Do I have to set up a mialbox for this?  or do I just follow the steps above for smtp and use pop connector to pop mail.  

Sorry I am probablly repeating myself here but I am just a bit stuck at present.

Thanks for help.
Stephen.

Hello,

Sorry, I misread your question, here is what you can do :

1) In order to use the pop3 connector, you need a  valid Exchange mailbox. So I would start by creating users accounts & mailboxes.
2) Configure the pop3 and SMTP connector on the Exchange Server. (Exchange System Manager/Connectors/)
Usually if you don't have a static IP, ISP's requires your SMTP Server (Exchange in your case) to use their SMTP relay server. In most cases it's smtp.isp.xyz so it could be smtp.eircom.net but check it with them.
This is done in Exchange System Manager/Connectors/SmallBusiness SMTP Connector/General and by setting the "Forward all mail through..." option with the correct (smtp.eircom.et ???) smarthost.
3) Leave your default policy (Exchange System Manager/Recipients/Recipients Policies) with an @ifp.local address.4) IMPORTANT : launch DSA.MSC and replace your users primary SMTP addresses (E-Mail addresses tab) with their real eircom.net addresses. If you don't do this, Exchange will send emails with replies addresses set to ifp.local.
I hope this can help you...

Hi

I created new users and mailboxes (deleted any old ones first).

I can know send mail using smtp, but as was mentioned my mail is coming up as irishflooring@ifp.local..

My mail is  poping from eircom internet domain, into my irishflooring mailbox but it is not appearing on clients pc?
Its like it is stuck in mailbox?

The other prob is that when I go into Ad manag, and into user and look at email address in user general section it appears strange. i.e irishflooring21197@ifp.local.
As was mentioned above it should be changed to irishflooring@eircom.net.  When I try do this I get the following an error like below

### Id ... this email address already exist in this organisation"
id "c10312e7" microsoft active directory- exchange extension##
 
When i go back into email it changes to e.g irishflooring23Deb@eircom.net
When change it back to irishflooring@ifp.local it gives above the above error but changes
ok/.

Hope i havnt turned a mole hill into a mountain :-)..

Thanks
Stephen

Hello,

This is not a real problem. Email addresses must be unique within the Active Directory. You cannot set 2 users account with the same email address. If you only have one "external" eircom.net address the easiest thing to do would be to create a dedicated user account such as "eircomnet_user" that has that address.
If other users need to access thoses emails, just give them access to it with Outlook.
If they need to do be able to send outgoing emails with your eircom address do the following :
MSA.DSC, right-click on the eircomnet_user account, seect Exchange General/Delivery Options and and users in the "Send on behalf" field.
In Outlook, open a new message, select the "View" menu and tick the "From" option and use it to specify from which account emails are being sent.
Don't lose hope...

Hi,
  Will give that a go straight away thanks very much, the only thing is the incoming mail is not appearing on client pc and I have only one user at present and it is still telling me "irishflooring@eircom.net address already exist in this organisation"

I orignally had a user set up with this before reinstall of exchage and deletion of users and mailboxes?  

Thanks again,
Stephen

Hello,

The problem is that you still have an object in the AD/Exchange that has the same "irishflooring@eircom.net" address. It can be a user, a contact, a group, a public folder,...
You have to search for that precise address, either by creating queries in DSA.MSC or Exchange System Manager.

If you are unable to do so, install the Windows Support Tools (they are on the W2K3 CD's) and run either of the following commands :

csvde -f mydomain.txt
ldifde -f mydomain.txt

It will create a text file in which should be able to identify the existing irishflooring@eircom.net address.

We've had that kind of problem and it can be resolved without having to reinstall the whole system !!!

Don't lose hope...

Hi,
  have not lost hope yet :-).

I have registered a domain, and I am going to set new mails up with that domain.  I need to have a domain set up for my company anyways.

The domain is hosted externally i.e mail.  So will I need any settings from them?
i.e external ip etc.

They have gave me  a few mail accounts as well. i,e info@irishflooring.ie
so i will set my server up with domain irishflooring and all should be ok I hope...

I could then pop my irishflooring@eircom into my new emai  account.

Will this procedure be fine?
Thanks again
Stephen
