My MS Outlook email and calendar font size suddenly reduced in size so it is unusable and won't change back to normal size.

I'd be grateful for any suggestions to resolve the problem please.

    If your Outlook email and calendar font size has suddenly reduced and won't change back to normal, there are a few steps you can take to troubleshoot the issue:

    1. Check Display Settings: Sometimes, changes in the display settings of your operating system can affect font sizes in applications. Ensure that your display settings (like DPI scaling) are set to the recommended values.
    2. Adjust Outlook Font Settings: You can manually adjust the font settings in Outlook:
      • Go to File > Options > Mail > Stationery and Fonts. Here, you can change the font size for new emails, responding, and forwarding.
    3. Reset Zoom Level: If you are viewing an email and the font appears smaller, try resetting the zoom level. You can do this by holding down the Ctrl key and scrolling your mouse wheel up or down.
    4. Check for Updates: Ensure that your Outlook application is up to date. Sometimes, bugs that affect font sizes can be resolved with updates.
    5. Repair Office: If the issue persists, consider repairing your Office installation. You can do this through the Control Panel under Programs and Features by selecting Microsoft Office and choosing the Repair option.

    If none of these solutions work, you may want to consider reaching out to Microsoft Support for further assistance.

    none resolved the problem - very poor suggestions and it seem nigh on impossible to contact MS support

    Hi, I understand how inconvenient that can be when everything suddenly looks tiny.

    This usually happens because Outlook’s zoom level or display scaling changed, not the actual font settings.

    Let’s start with the basics: open an email and check the zoom under Format Text then go to Zoom, set it to 100%, and tick “Remember my preference.”

    Also, try holding Ctrl while scrolling your mouse wheel in the reading pane or calendar to adjust the view.

    If the calendar still looks small, check your Windows display settings under Settings then go to Display then click Scale and Layout and set it to 125% or 150%. Quick question, does this happen only when reading emails, or is the entire Outlook interface, including menus and calendar, smaller than usual?

    Regards,

    Aron
