 Exchange redirect problems
Hi all, I've recently implemented Exchange 2003 in my customer's main office, in this office all the users are working correctly with Outlook. The problem appears when they are sending e-mails to other users from another offices (these external offices are not working with exchange server but working with the ISP mailbox directly), exchange can not send the email, because it's not able to find this external user. Could be solved with any kind of rule into Exchange??? All the users from all the offices are working within same domain "@aaa.com" Thanks very much in advance!

Answer Wiki:
How can both internal and external email addresses have the same domain? My company domain of me@mycompany.com is different than my isp which is me@att.net. att isn't going to allow my company use att.net and my company could not use mycompany.com if we were using the isp email address. Can you explain this a little more clearly? Perhaps this is why there is a problem. <a href="http://itknowledgeexchange.techtarget.com/profile/Alessandro.panzetta">Alessandro Panzetta</a> Here the only solution i see at the moment is to rebuild the Exchange domains with somethin like <i>yourdomain.local </i>instead of the real <i>yourdomain.com</i> and then have the POP3 connector download the messages to the user's mailboxes. You can then set the default SMTP address to be <i>yourdomain.com</i> instead of <i>yourdomain.local</i>. Bye This is the final solution I found from Microsoft Support. I will test it as soon as possible but it's exactly the problem I have: <a href="http://support.microsoft.com/kb/300681/en">http://support.microsoft.com/kb/300681/en</a> Thanks!

Just a question, when the users from OfficeA are sending the email to OfficeB, are they writing the user@officeb.com or simply “user”?

The users from officeA, are using the whole address, not the “user”. The domain for all users (internal/external) is the same. I think I found a solution from Microsoft to send e-mail to external users.

Ok sorry if I didn’t read better your answer before, anyway it’d be kind of you if the solution can appear on this site too so the knowledge is shared.

Hi Technochic,

Sorry, maybe I explained it not very well. Everyone in our company uses the same domain…for example mycompany.com. In the main office I’ve recently implemented exchange server 2003 with the POP3 connector for every user in the main office and it works OK.

They can send and receive emails normally, but when somebody (user1@mycompany.com) wants to send an email to a user (user2@mycompany.com) of another office of the same company (this other office is not working with exchange server 2003).

Outlook (exchange) is not able to send this email to the recipient because this address does not exist (user2@mycompany.com is not configured in exchange of the main office).

I hope it’s more clear now.

Thanks,

I think I am starting to get it, it’s still confusing to me how another office can have the same email domain name when they are not on the same exchange server? Domain names are purchased and MX records are created for the exchange server to identify the exchange server to the rest of the world.
Did you create MX records for your exchange server?
When your users try to send to the other office, and it fails, what is the exact NDR (non delivery report) that they receive back?
Can your exchange users send to any external email addresses at all besides the other offices?

Hi Technochic,

We have HOSTING (mail and web) service with an external ISP, a POP3 connector is defined in exchange server for each exchange user, so the systems checks the email from the external ISP hosting every 15 minutes automatically.

This is the NDR: (translation)
“Unable to reach the following recipients:

user@ourdomain.net en 27/05/2008 10:30

The email address does not exist in the organisation where this message was sent to. Check the mail address or contact the mail recipient”

Kerry,

I think what you need to do is tell exchange that this isn’t the default box for the domain or forward unresolved (i.e. not in exchange) users to your ISPs mail server which will forward them on.
