  1. Win 10 ‘mail’ is buggy in display capabilities, but it CAN be set to full-screen display without a reading (preview) pane. I can’t see how to attach an image, but I can send it if needed.

    To get there required some tinkering with a combination of: (1) window mode (restore down), (2) compact message spacing (under Settings > Personalization), (3) expanding or contracting the accounts pane (≡ at top left), (4) dragging the window at the sides / top / bottom to fill the screen, and (5) repositioning the window if necessary. It may take a couple of attempts, but the message display then changes from the multi-line compact mode to a 2-line (ultra-compact) mode with pop-up symbols (archive /bin / flag) at left and text preview (if on in settings) towards the right (before the date). Somehow this became the default view for me when ‘mail’ opens. Double-clicking opens the message in a new full-screen window. Great!

    But when I tried to get the same thing for another account on the same computer, it only works for the session (in the expanded window mode, which is no really a full-screen mode). Then it defaults to an ultra-compact mode but with the reading pane when re-opened (as full screen).

    I can’t find where mail window settings are stored. But this experience may be a clue for those more skilled in such matters. It could interact with other tweaked settings, in Win10, but I don’t think so.

  2. If mail defaults to to the ultra-compact mode (actually 1 line per message) but with a reading pane when re-opened (as mentioned above): The nearest work-around I found is to make the expanded window for mail (as mentioned above) just smaller than full screen (experiment with how much smaller if necessary: don’t make it touch the screen edges). Then mail will re-open to the same configuration from a shortcut that has Properties > Run : Normal window. And selecting a message will open it in a large new window. Great!
