The Hub Transport connectors know how to talk to each other. If the failures are happening on those HT-to-HT connections it may be that you don't have the correct SPNs set. Do you have eventID 2017 (from the source MSExchangeTransport and category SmtpSend) in your Application event log? On each of the machines, run "setspn -L

The response from the remote site is 454 4.7.0 Temporary authentication failure Event ID: 1035 is logged when some e-mail messages are stuck failed with error in a remote delivery queue in a Microsoft Exchange Server 2007 environment or in a Microsoft Exchange Server 2010 environment. Cause: This issue occurs if the Exchange server cannot authenticate with the remote Exchange server. Exchange servers requires authentication to route internal user messages between servers. The issue can be caused by one of the following reasons: The Exchange server is experiencing Time synchronization issues The Exchange server is experiencing Service Principle Name (SPN) issues The required TCP/UDP ports for the Kerberos protocol are blocked by the firewall. To resolve this issue, follow these steps: Check the clock on both servers and domain controllers that might be used to authenticate the servers. All clocks should be synchronized to within 5 minutes of one other. Verify that the Service Principle Name (SPN) for SMTPSVC is registered correctly on the target server. Make sure that the SMTP and SMTPSVC entries are added correctly to the machine account by using the SetSPN tool.

Solved Mail flows one way from one 2007 box, but not vice versa Posted on 2011-03-09 Exchange 1 Verified Solution 4 Comments 1,874 Views Last Modified: 2012-05-11 Hi, I currently have two exchange servers in two sites. The plan is to move all mailboxes from Site A to Site B so we can decomission the server, but this is a project that will take a few months to complete so both servers need to send mail back and forth depending on where users mailboxes are. Site A is old site, Site B is the new. Site A has User A in its mailbox DB Site B has User B in its mailbox DB User A can send mail to User B, external can send to User B BUT User B cannot send to anyone at Site A, but can to others at Site B The messages sit in the queue and report "4.4.0 Primary target IP address responded with: “454.4.7.0 Temporary authentication failure.” Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts or deliver failed to all alternate hosts. " In the eventlogs the Transport Service throws Error 2017 "Outbound authentication failed with error TargetUnknown for Send connector Intra-Organization SMTP Send Connector. The authentication mechanism is ExchangeAuth. The target is SMTPSVC/externalFQDN.domain.com" externalFQDN.domain.com is what users use for connecting to OWA etc so has been changed for security. What I dont understand is why it appears to want to go the external route, and not through the internal route to server.domain.local at Site A. Any help that anyone can sug
