Please revert the Outlook for Mac reading pane Dark Mode setting back to what it was in v16.26 (app in dark mode, reading pane in light mode), or create this as a preference that can be user toggled - not on or off for the whole app as is currently the case. Toggling the setting for every single email is a joke - no HTML emails or signatures have been created with dark mode in mind, looks terrible.
