NDR's on valid email addresses

We had to reinstall and restore our Exchange Server due to the fact that we had to recreate our domain. This is a long story but basically we experienced some AD corruption issues and was on the phone with MS support for three days. What seemed to them as the quickest way to remedy the corruption has turned out to be one problem after another.

Everything seems to be working okay with the new Exchange Server except for one very important thing, external email. We are able to send email externally and receive email from the external, for the most part. Only some of the email addresses attributed to users and all of the email addresses attributed to public folders are bouncing back with the following:

The following recipient(s) could not be reached:

      'user@domain.com' on 5/3/2005 10:51 AM
            The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address.
            <server.domain.com #5.1.1>

Even if I send and email internally to the internal SMTP email address it will fail. In tracing the message in message history I get:

SMTP Store Driver: Message Submitted from Store
SMTP: Message Submitted to Advanced Queuing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer
SMTP: Message Categorized and Queued for Routing
SMTP: Non-Delivered Report (NDR) Generated

I'm at a loss. I've tried removing the email address from the user and re-adding it without any luck. I don't understand why some email addresses will work but then not others. Any help would be appreciated!

did you recreate the users in the domain, or did you somehow migrate the information to the new server?

You may be missing a few pieces to the user account.

Open up ADSI editor on your exchange server. View the properties for the user and check the alias and mailNickname attributes.

Thanks for the prompt response, athelu.

We migrated AD using ADMT and then created the new container, restored the container and associated email accounts with AD accounts using the Mailbox Recovery Center.

In reviewing the users through ADSI, they are in fact missing some of their email addresses. If I add the SMTP address value manually to the proxyaddress attribute, the emails go through okay! The only problem is that I'm looking to add around 200-300 entries. Does anyone know of a utility that would help me? Like I mentioned before, the email addresses are showing up in Exchange System Manager but not in ADSI.

What about the public folder email addresses? The public folders don't show in ADSI.

Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

 
atheluCommented:
yes. Virag is correct. ADmodify is a tool you can use to make mass updates to multiple accounts in AD at once. It has support for variables, so it could automatically generate the missing information for you. I am not sure however if it has the ability to modify Public folder variables.

here is a url to the version on microsoft FTP server

ftp://ftp.microsoft.com/PSS/Tools/Exchange%20Support%20Tools/ADModify/

I ended up adding all of the email addresses manually in ADSI proxyaddress variable. For the public folders I just deleted them and recreated.
