Chuck Hildebrandt, I also have issues with the new look, but confused by your last two comments:
- It looks like slightly MORE fits on your screen in the second screen shot you posted compared to the first, but you complained that less fit.
- You said, "they finally took the old look away..." This is not live yet, unless you opt in to view the preview. Presumably that's so MS can get feedback like yours and mine and make changes before they do finalize.
Note that even in the preview, you can flip between the the full Ribbon bar, the retracted Ribbon, or the new Compact Ribbon bar. Because that's just an added option (the Compact one is new, the other two we've had for years), I don't see any downside to that particular part of the update.
I also keep an Outlook window always up in a separate monitor in Portrait mode, just like yours. My complaints are around the lost ability to have one window show the full ribbon and another have the ribbon hidden (a feature of the current production Outlook) and that in new messages or meeting invites, the header space is HUGE leaving much less room for the content of the message, even with the more compact ribbon. For those reasons, after reporting my problems to MS, I have reverted back to the production version and am not using the preview. I chronicled the steps to do this above (it was admittedly painful).
