Microsoft has updated the Exchange Remote Connectivity Analyzer site with the option to analyze message headers.
I had blogged earlier about analyzing message headers using mxtoolbox. Now the same option is available in ExRCA.
Paste the message header and click on “Analyze headers” button to get the output.
There are many free tools out there which does the same job. But, it is nice to have it built into one of the most frequently used troubleshooting tools.
