Moving mailboxes stops mail flow - Exchange 2003 to 2010
Posted on 2014-02-15
I have setup an SBS 2011 server with Exchange 2010. I have in use an Exchange 2003 server that is being decommissioned.
I have transferred the rights and all other settings to the 2010 server and I am now moving the mailboxes.
Unfortunately this is taking a LONG time due to the sizes of the boxes. While these boxes are moving I was under the impression only the box (or boxes) currently in the process of actually moving would not work while the rest would.
1. ALL mail is being held in queue and not being delivered.
2. A box that was already moved continues to ask for a password in Outlook with no result.
3. Using the mail flow troubleshooter provides the following results:
The 'Remote delivery' queue (LUEMAILSERVER\74) on server LUEMAILSERVER is in retry status. Number of message(s) in the queue: 1. Last error information: 451 4.4.0 Primary target IP address responded with: "421 4.2.1 Unable to connect." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts.
Server mail.guiderail.com is a remote server to which server LUEMAILSERVER is trying to send messages but no 'Host' records of server mail.guiderail.com can be obtained from any DNS servers server LUEMAILSERVER uses. This may be causing message backups in the queue.
The computer account for Exchange server wfs1.luinc.guiderail.com does not appear to contain the fully-qualified domain name of Exchange SMTP virtual server 'Default SMTP Virtual Server'. This may cause Kerberos authentication to fail when sending messages between servers. The tool expected to find 'SMTPSVC/mail.guiderail.com' in the ServicePrincipalName.
Remote server mail.guiderail.com failed the mail acceptance test. MAIL FROM command: Respond = 530 5.7.1 Client was not authenticated.
mail.guiderail.com is the public name and CAN be resolved via pinging/traceroute/etc.
WFS1 is the old server and LUEMAILSERVER is the new server.
Mail CAN be sent out and IS received by outside recipients and mail IS being received just held in queue.
Please advise. Thanks.
