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.
- Open up the Message Analyzer tab of Microsoft’s Remote Connectivity Analyzer in a browser window.
- 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.
- Flip back to your browser, and paste the message header into the Message Header Analyzer area.
- Click Analyze Header and you will get a Summary report, plus a list of Received Headers and other headers.
