We are in the middle of a migration from Exchange 2003 to Exchange 2010. I see there that there are over 100 items in the submission queue for Exchange 2010. All of the items are from the same address (exchange_server_name-IS@d
to the same recipient address (firstname.lastname@example.org). All of the messages have the same error:
Subject: Folder Content
Internet Message ID: <012033945802AC4AB8DF73C9A
From Address: echange_server_name-IS@dom
Size (KB): 42
Message Source Name: SMTP:Default CAS01
Source IP: x.x.x.x
Date Received: 4/25/2011 4:03:09 PM
Expiration Time: 4/27/2011 4:03:09 PM
Last Error: 420 4.2.0 RESOLVER.ADR.Ambiguous; ambiguous address
Queue ID: CAS01\Submission
I went through the following links:
When I do an LDAP search for the email recipient address (email@example.com) it doesn't come up in the search. I confirmed my syntax was correct by finding an account that I know does exist.
I did find SMTP addresses on the System mailboxes in the storage groups of the Exchange 2003 server that had similar addresses like firstname.lastname@example.org & email@example.com, so I'm wondering if the address firstname.lastname@example.org is a remnant.
Any help would be appreciated.
