Need email "View Source" back
"View Source" was an important tool for looking at the source (headers, body, servers, etc.) of a received message. It was in the context menu (right-click) but is no longer there. I could not find it in the menus either.

As others have commented, this is one of the single most important features of use to email admins. It's a basic and fundamental feature and should be one of the first available tools in the client, rather than being one of the last.
This is one of the most basic features of any email client. Needed for troubleshooting email routing or performance issues and for verifying source for fighting phishing.
There is an Addin "Message Header Analyzer" you can use to view the headers.
This is not an optional feature. It is necessary when determining the provenance of an email, for fighting phishing attacks, etc.
