Outlook (Microsoft 365 / Windows 11) shows all emails — Reading Pane and composing new messages — in a strange font; forwarding or copy-paste shows Aptos; tried clearing caches, reinstall, new profiles, and font settings — nothing works, need hotfix or profile rebuild.

Classic Outlook has many options that control the appearance of the user interface. To find them all, click View Settings on the View tab (see the screen shot below).

That said, what you describe doesn't immediately strike me as the result of a particular view.

If you are saying that all of your e-mails have the same font, it sounds more like plain text format has been enforced for all e-mails. Are you able to see italic or bold in messages that you send or receive?

    It seems that the issue you are experiencing with strange fonts in Outlook's Reading Pane and while composing messages could be related to missing fonts or font settings after upgrading to Windows 11. When Windows is upgraded, certain fonts may not be available by default, as many of them have been moved to optional features to optimize disk space and performance.

    To resolve this issue, you can check if the necessary fonts are installed and enabled:

    1. Go to Settings > Apps > Optional features.
    2. Look for any missing fonts that you might need and install them.
    3. Ensure that the permissions for the C:\Windows\Fonts folder are set correctly, as incorrect permissions can also lead to font issues.

    If these steps do not resolve the problem, you may also want to try adjusting the ClearType settings or disabling subpixel positioning in Word, as these can affect how fonts are displayed.

    If the problem persists, consider rebuilding your profile or reaching out to Microsoft support for a hotfix specific to your issue.
