High DPI support for inline images when creating and reading email
While text is scaled properly when reading or writing email in Outlook, inline images are not. Inline images within a message sent from a PC with 100% display scaling will appear too small when viewed on a PC with 200% display scaling, such as on the Surface Book. Conversely, images within a message sent from a PC with 200% display scaling will appear huge when viewed on a PC with 100% display scaling. Also as users have 4k screen and when they “Open in new window” to open a secondary window, such as a calendar the new window opens as a small window in the top left quarter of the screen. It seems that the new window size is a fixed number suitable for a 1k screen when it should be adaptive to the screen size.
This is especially a problem when inline images are screen shots and text is part of the image. This results in text being either too small to read or unnecessarily large.
This is not a problem when viewing the same email through a web mail interface because the browser (Chrome) handles scaling properly. Can Outlook 2016 act more like Chrome in this regard?

I have a 4k monitor that I'd *like* to use at native resolution (3840 x 2160), but Outlook 2016 scales in such a way that Outlook is nearly unusable. For example, when scheduling a meeting with others, the viewable timeslots are SO TINY that I'm unable to accurately select the right meeting time or location.
If you're not going to 'automagically just make it work', I should at least be able to disable or manually adjust app scaling for Outlook so it's usable.

I use Outlook 2016 (and all of Office 365) all the time. It seems that the lastest versions of OUtlook and Excel have an issue when rendering on a 4K monitor. Many times r the scroll bars go black or screen artifacts remain long after closing a window and re-opening it. I am getting the issue on both my Surface Pro 4 and my ThinkPad P70 ... same issue ... same poor graphics and since my graphics chips are totally different between the two machines I figure it has to be an Office 365 issue.

Same for pinch-zoom interface. In outlook, it only affects the text zoom. I'd expect it to let me zoom everything together, text and images included, like in Onenote. The most frustrating experience is when I pinch-zoom over a rendered image and it's just the text zoom that changes.

In the weekly calendar view, I'd like to have finer-grained zoom levels so that I can optimize how much information shows up on my 250+DPI laptop display. Right now, I use 110%, which shows 15-minute increments, but I'd like to be able to shrink it down so I can see a full day without scrolling.

please provide an option to scale the outlook user interface for non-touch screen use (mouse). It is far too large for a typical 1920x1080 screen environment. thank you!

Advanced Find Dialog (Ctrl+Shift+F) is far too short: half the controls are clipped and not accessible. My laptop monitor requires 250% scaling. (Incidentally the forms on this website wrap at only 2/5th of the available space!!) Time to splash out on modern hardware for your developers? Reason I got 2016 was I was hoping for reasonable HIDPI support.

I have a Surface Pro 3 and when I dock it to use my external monitor (1920*1200) all of Office looks blurry. I need to sign out completely when moving between screens to solve this. Other MS Applications don't seem to suffer from this problem.

If running across multiple monitors at different screen scaling (e.g., 100% and 150%), Outlook only appears cleanly on one screen. The other is scaled and fuzzy. With modern devices like Surface, this is a common scenario and a real problem. For example, I like to keep my Inbox full screen maximized on one monitor and do most of my work on the other. In UWP apps, this works perfectly across different scaling monitors. Please fix in Outlook.

On a High DPI monitor, the Advanced Find window is not large enough to show all of the options, and you cannot resize it to make it larger. This prevents you from using a lot of the options and make the search worthless.
This problem was reported over 2 years ago on Office 2013, and it persists with Office 2016. (http://answers.microsoft.com/en-us/office/forum/office_365hp-outlook/outlook-2013-outlook-2016-advanced-find-windows/7bd1f3c8-955e-4c7d-90dc-522c0a7429f2?auth=1)

Display scaling does not work for advanced search and query builder

My external 1080p monitor I run at 100% dpi scaling while I run my 1080p laptop at 125% scaling since at 100% the font is too small to read.
When I undock my laptop from my monitor, all of Outlook is somewhat blurry/fuzzy since it doesn't seem to adjust to the dynamic dpi scaling the way that UWP apps seem to, or Skype for Business does.
My request is to make Outlook support dynamic DPI-scaling so that I can support this scenario without one of them looking blurry.

I think this might actually be completed in the latest builds of Outlook 2016.

There's a problem currently with viewing images in emails on HiDPI screens that use scaling... The images are too small and aren't scaled up as they should be with everything else. All content in HTML emails should be properly scaled.
