Hotmail.com Emails Have Larger Margins

Within the last couple of days, all my emails in my hotmail.com account, no matter the formatting, and no matter how old they are, have much wider margins, left and right. So the text of the email is more compact, squished. Why did this happen? And how do I get my email margins back to what they were? And zooming in or out doesn't change anything.

When I hit reply, the margins go back to normal.

    Outlook.com has no separate control for message-body margins, so change the Reading pane to Bottom or Hide to restore more horizontal space for messages.

    Change the reading layout

    1. In Outlook.com, select Settings (gear icon).
    2. Go to Mail → Layout.
    3. Find Reading pane.
    4. Select Show on the bottom and reopen a message.
    5. If the text is still constrained, select Hide and open the message in its own window.

    Microsoft documents Right, Bottom, and Hide as the available reading-pane positions; display density changes spacing in the message list, not margins inside the message body.^1^

    Because old and new messages are affected while the reply editor remains normal, this is a reading-view issue rather than formatting stored in the emails.

    Check whether Immersive Reader is active

    If the message appears in a focused or full-screen reading view:

    1. Press Esc, or select the back arrow, to leave Immersive Reader.
    2. Reopen the message normally.

    Immersive Reader can change text size and spacing and is separate from the reply editor.^2^

    If every Outlook.com element has changed size

    Reset the browser zoom:

    • Press Ctrl+0 on Windows or Command+0 on macOS.
    • Alternatively, open the browser menu and set Zoom to 100%.

    Outlook.com uses browser zoom for changing the reading size.^3^

    If the mailbox controls remain their normal size and only the opened message has wider margins, browser zoom is unlikely to be the cause. If none of these changes restores the previous width, use Help in Outlook.com and report it as a reading-pane layout change; Microsoft does not currently document a dedicated setting for reverting message-body margins.

    Hi @Steven G

    First, please check the AI answer

    Since the wider margins affect both old and new messages, while the reply editor still appears normal, the original formatting of your emails has most likely not changed. This sounds more like a rendering issue in Outlook.com.

    Please try opening Outlook.com in an InPrivate or Incognito window. If the messages display normally there, a browser extension or stored site data may be interfering with the reading view. You can then disable extensions one at a time, especially ad blockers or page-formatting extensions, and clear the site data specifically for outlook.live.com.

    It would also be useful to test the mailbox in a different browser. If the same margins appear in multiple browsers and devices, the change may be coming from Outlook.com itself rather than from your browser settings.
