The 'Message Header' is the area above where the message content of an opened email is displayed. It typically contains a set of buttons - Reply, Forward, Archive, Junk, Delete and More It shows From, To, Subject and Date It may show other information depending upon settings and type of email.

Do you find the spacing between eg: the 'From' line and the 'TO' line is too much? Do you want to reduce this gap? If yes, then the following information may solve your problem.

Have you discovered that you cannot raise the 'Message Pane' as far upwards as in previous versions? This is because the developers have increased the minimum height of the Thread Pane otherwise known as 'Message List'.
