When opening my mail (Outlook/Hotmail), the righthand scroll bar keeps disappearing. I try to moved the screen to the left, but it does not work. How can I adjust my settings to ensure I always have a RH scroll bar?

    Hi thebeachisgud,

    If the scrollbar is disappearing consistently, an additional thing to check is whether the issue is tied to your current Outlook or browser display settings rather than Windows scrollbar behavior itself.

    Try resetting the page zoom level:

    1. Open Outlook/Hotmail.
    2. Press Ctrl + 0 to restore the browser zoom to 100%.
    3. Refresh the page and check whether the scrollbar remains visible.

    If the issue only occurs in one browser:

    • Open Outlook in a different browser or an InPrivate/Incognito window.
    • If the scrollbar appears normally there, temporarily disable browser extensions (especially UI customization, ad-blocking, or accessibility add-ins) and test again.

    These checks can help determine whether the scrollbar is being affected by browser rendering or display customization rather than the Outlook page itself.

    For Outlook/Hotmail on Windows, the supported setting is to make Windows keep scroll bars visible:

    1. Open Start > Settings.
    2. Go to Ease of Access > Display.
    3. Turn Automatically hide scroll bars in Windows to Off.

    If the scroll bar is still missing in Outlook, restore the app window:

    1. Right-click the Outlook title bar.
    2. Select Maximize.
    3. Right-click the title bar again.
    4. Select Restore.

    If the issue is specifically in Outlook 2016 and the view jumps or scrolling behaves incorrectly, Microsoft lists it as a known issue that was fixed in certain builds. For Current Channel, a registry-based workaround exists. Warning: editing the registry can cause system problems if done incorrectly.
