Outlook clients (on Windows, macOS, iOS, Android and Outlook.com) will automatically adjust your colors into a dark mode and force them to be WCAG compliant and have a 4.5:1 contrast ratio.

A solution to maintain your background-color if you absolutely must is to use a background-image of a single pixel of the color you need. (This won’t work in Outlook on Windows because it doesn’t support background-image.)
