Can't reply to old email after migration

I had a WinNT 4.51 SBS with exchange. I exported all the exchange mailboxes using exmerge.exe. I then upgraded to 2000 sbs, brought in 2 windows 2003 servers after I prep'd the domain. Long story short, I basically migrated the 4.51 sbs domain to a 2003 domain. Took a long time but it worked. Anyway. Once done I installed exchange 2003 and imported all the mailboxes. Now here is the problem. When the end user goes to reply to an email he/she received from an internal user prior to the upgrade, the email gets bounced back with no reason. If you click reply, and then right click over the name and click properties, there is nothing in the email addres tab. Now, if you create a new email, and selected them from the GAL, it works fine. Just a problem with emails received prior too the upgrade, and only ones received from internal users. Any ideas how to fix this??? Any and all help is greatly appreciated.

Thanks,

Woody H

Did the organization name change?

Also, how did you associate the old user accounts with the new user accounts?

Nothing changed. I kept the domain name and organization name.

Exchange uses X500 addresses to send emails internally. If the server name, domain name or anything else changes, then old mail addresses will not work as the mailbox location has changed.

For the time being, either avoid replying to old messages or if replying, delete the To address, and reenter the recipients name from the GAL.

The only thing that did change was the server's name. Nothing within exchange changed though. They are stuck using the reply and changing the reply address to what is on the GAL. Since yours is closest. Congrats.

I didn't create new user accounts. The accounts exist from the old domain, I migrated the domain over. The only difference is the exchange server install. I installed exchange and then used the exchange tasks wizard to give everyone back their email addresses.

As far as the x500 address. It is still the same, the domain name didn't change. Would installing an entirely new exchange server still cause this problem?
