For people that do proactive threat hunting, (screening traffic for Bad emails that delivered), we depend on the capability to quickly view email headers for simple red flags such as a blank To: field or suspicious file attachment names/file extensions (Doc.htm for example). As of this morning, the email header details are collapsed by default. Is there a way to pin the email header details, so it goes back to displaying all the time? It is very time consuming to have to expand every email you screen to view the header. For those that only use the message log to view an email that they already know about, it is not a big deal. But for those that screen traffic in near real-time, adding a time consuming click is counter productive.
