Tool to Analyze Message Headers

Microsoft’s Remote Connectivity Analyzer is a great resource tool for testing and running diagnostics against Exchange, ActiveSync, OWA, POP3/IMAP, Lync, and Office 365. It also includes Message Analyzer, which is an SMTP header analysis tool and makes reading email headers less painful.

Microsoft’s Exchange Team has a good blog post on how to use the Message Analyzer feature.

For grins and giggles, I sent myself and email from my Gmail account to my business email account, and then processed the message header through the Message Analyzer.

  1. Open up the Message Analyzer tab of Microsoft’s Remote Connectivity Analyzer in a browser window.

  2. Open up your email client and access/view the message header. Select and copy the complete contents of the message header.
    I have a separate post that explains how to view email message headers from Outlook 2010/2013.

  3. Flip back to your browser, and paste the message header into the Message Header Analyzer area.
