How can I view the logs in Exchange 2010 to determine why incoming emails have been getting rejected?

How can I view the logs in Exchange 2010 to determine why incoming emails have been getting rejected?

Another company keeps trying to send users within my organization emails but these emails are being received by my Exchange server.

I need to be able to view the logs to determine why my Exchange server isn't receiving these emails.

I would start by running the Exchange troubleshooting Assistant available under tools. This wizard will help you find the logs covering the failed transaction.

You can also and as you specifically asked, review the logs directly, refer to the following for information on how to do this


hope it helps

You can check your exchange server health your using tool Mail Flow Troubleshooter. It will show if your exchange have any issue in mail flow

Alternative:- ask that company administrator to send you the bounce mail on your another id i.e. gmail/yahoo etc. That bounce mail should have reason of bounce.
If you have spam agents enabled you can use the get-agentlog cmdlet, if it's a spam agent causing this to happen it will tell you so... Play about with this cmdlet as it's really Usefull especially when piped to export-csv

Other than this set your receive connector to verbose and check through
the SMTP transcript under transport role

Set-ReceiveConnector “Connector Name” -ProtocolLoggingLevel verbose

Finally you can use tracking log explorer under tools in emc

There are two sides here, sender and receiver so it might not be within your admin boundaries. Try and post an NDR here if you can get one and consider any other spam filters between your exchange and the Internet such as services like mime cast or messagelabs
