The headers of a message are detailed information on the routing of a message. Because they contain information than most would need or want they're usually available but hidden.
Because seeing the headers of a message are such an immense help to troubleshoot email related issues we thought we might share how to find them for some of the more popular mail clients.
How to find email headers by client:
From the Email -> go to top right corner click "more" dropdown -> Select View Source
Highlight the message -> Go to View at the very top -> Message -> All Headers
Double click the message so it opens in its own window >> Go to File>>Properties -> Headers are displayed in properties box near the bottom
From the message go to the upper right hand side >> Click the 3 dots>>Select Show Original
From email message >> Top center next to "Spam" click 3 dots >>click View Raw Message
Highlight email message >> Click the 3 dots with "More" underneath>>click Show Source
Click Message >>In message screen go to top right hand side >> Click the dropdown >> Select View message source
Highlight email message >> Mid Screen Click + symbol >> View Source
