Hi Graig, KB 284204 notes the following about the 4.4.7 error message: Possible Cause: the message in the queue has expired. The sending server tried to relay or deliver the message, but the action was not completed before the message expiration time occurred. This NDR may also indicate that a message header limit has been reached on a remote server or that some other protocol timeout occurred during communication with the remote server. Troubleshooting: this code typically indicates an issue on the receiving server. Verify the validity of the recipient address, and verify that the receiving server is configured to receive message correctly. So the problem is usually on the recipient’s server. Common causes are the recipients mail server is offline or otherwise unreachable, possible due to DNS problems. But you can perform the following steps to ensure whether the issue is on your side: 1. Use a other account send an e-mail to the specific user. If the message will not deliver to the recipient’s server, it means that there is something wrong in the recipient’s server. 2. Telnet the recipient’s server from the edge server and it will get back an error. The error will help us know about the issue clearly. Here is a reference for you, http://support.microsoft.com/?id=284204 If you have any questions, please feel free to let me know. Best regards, Yang
