Greetings Experts,

1.      Had an old SBS 2003 server with about 10 users .
2.      Configured new SBS 2011 server.  Instead of migrating users, I created new domain and re-created users.  Imported PST files into each mailbox.
3.      Joined each computer to the new domain and setup Outlook.
Problem:  Mail looked like it was working fine, until internal users started getting bounce backs to other internal users.  External mail seems to be unaffected.
In the Bounce back e-mail: Each users is listed with the following error:
The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.

Then:

#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

I found a lot of people had similar problems, it’s related to old x500 e-mail address from 2003 server.  

They say to add the x500 address to the problem account, but I can’t figure out exactly how to get the x500.  I looked at the old server and it has a x400 e-mail.

Any help would be great.
Thank you,
Kacey

Does user have contacts added in their PST which may be pointing to old email address.

no, I checked.  this is happening to a couple users who don't even use the contact list.  I read that some of the people solved this by clearing the cache, but since this is a new account I figured that wasn't the problem.

It this happened on a newly email or they use to forward or reply from exisiting email (exporting PST). I had experiance before where after migration the user did used to reply and forward old email (from old server). For new email, it is no problem. If this a case then you have to 2 options:

1. Ask user to use newly email.

2. Set the LegacyExchangeDN by cmdlet Get-Mailbox <username> | Set-Mailbox or put X500 on Mailbox tab

It looks like this worked.  Go to an e-mail sent from the old server.  Right click on the e-mail address and click properties.  Then copy the x500 e-mail and create a custom e-mail on the new server for each user.  

I'll let it run for a day or so, then I'll accept the comment.
Thanks Suri
