Ok, new problem popped up today.
In Exchange 2003, we are experiancing a weird problem.
I can email one of our employees by directly emailing firstname.lastname@example.org.
But for what ever reason, we can not do a reply from an email from this user.
When we do a reply, we get the following error back
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.
<ourdomain.com #5.1.1 smtp;550 5.1.1 email@example.com: Recipient address rejected: User unknown in virtual alias table>
Anyone have any suggestions besides deleting this user's account and re-creating it?
His account has been fine for years until now. No configuration changes have been made to the system lately so i'm unsure of what could have happened.
Can you do an AD attribute dump of the user? It sounds like one of the key attributes required for Exchange may be missing or corrupted (I'm thinking maybe legacyExchangeDN given that it's a reply issue).
One way to do this is to use ADFIND from www.joeware.net, e.g. if the user's logon ID is"BobC":
adfind -default -f "(&(objectClass=user)(objectCategory=person)(samAccountname=BobC))"
I tried the ADFIND & it works well. I have the same issue of users sending email out but when someone
wants to reply, the message is returned with
User unknown in relay recipient table
Have Exchange 2003 SP2 installed. Cannot seem to solve this issue. The
legacyExchangeDN seems OK in that the info is correct. Anyone have this problem?
Our domain is getting this error when sending to a specific domain outside our company.
We filter our e-mail with an external provider (MX Logic) and suspect this could be part of the problem.
We can send to the same SMTP address from an external service provider (hotmail) but e-mail is rejected when sent from our Company(@titanspecialty.com) to one specific Company(@swsi.com)
Below is the bounce back message:

Hi Tony, I have had the same problem pop up this week. Exch003 all working fine receiving email to alis address and primary addrersses alike. This week however, no email aliases are receiving email, all bounce with error 5.1.1 user unknown. ADFind shows all of the email addresses as Proxy addresses, no corruption is evident.
Have tried deleting the secondary addresses, waitin ten minutes, putting them back, no joy.
I suspect that this may be a paid call to microsoft!
This particular server has been stable for three years, nothing has been changed.
Any clues greatly appreciated.
