Outlook 365 Client and modifying Header window in preview pane

HI Experts,
In Outlook 365 client, if my preview pane is on the bottom the 'heading' window for the email is rather large and takes away from my viewing of the email content window.
I can't seem to find out how to modify (if i can in O365) the size of that heading window.

Is there a way to do it, or even if there was a way to customize or minimize the font's used in that window and not the 'Body of email' window...

There is a little arrow lower right of this header. Set it to face down. Try it both ways and see that it changes the "header" size.

That is about all you can do with native Outlook.

OK thanks John,
Yes was aware of that arrow to modify the window but that only removed the date line I believe so not a huge difference.

but ok thanks for confirming that there's really not much modifying of that window,
