Using Two Domains in the Same profile of MS Outlook

I am running MS office 2007 with Exchange server 2003; currently we are using two different domain names on the same server with no problem example: ( and
There are some users that have to represent both domains without any one on the outside knowing.  
Currently the way their doing it is logging in and out of two different profiles, but now I have to configure their Outlook client to support both domains in the same profile so that that the users can send and receive from both domains what would be the best method of doing this?

There are two options.  
1. Create two email address accounts and then add the second one onto the user (go into email account and select advanced and add an account to open)

2. Or forward the mail from one acount to the other.

For both options you may need to add the 'from' box in Outlook by opening a new mail and selcting 'from' in the menu (depeands on outlook version.  For 2007 click on 'options' and 'show from')
You can now pick your from address.  From memory both of them should get replies from the right account if the name was in the to list.

This didn’t, work whenever I would send an email it would show that it was sent from the profile account on behalf of the second domain but I can’t let this show so I think I'll use IMAP


If you list two accounts in main section under tools / email accounts you get an 'account' button to select which one to send from when you send a mail.
You cannot have multiple exchange server accounts but you can add an POP/SMTP server.  This way you can have your main account as the exchange one.  If you click reply without changing it will go out as that account.  If you slect the other account here then it will go out as that one.
I used this ages ago for something similar.
I set the incoming pop server to be something non-existant like 'none.none'
Then under send/receive menu I disabled receiving on this account in online and offline so it would never even try.
This only covers the sending.  For receiving I used the stuff further up about adding another account under advanced settings.

The only thing extra you need here is an SMTP server (which the exchange server can do, or you can set up a freeware one)
