Targeting Outlook.com with CSS/Conditional Statements in 2022?

Question

I'm having a serious problem sending emails, specifically the browser version of Outlook (webmail).

All solutions that worked in the past no longer work in 2022:

[owa] .foo {
  background-color: red !important;
}

[class="x_foo"] {
  background-color: red !important;
}

I've also tried various conditional tags, but they don't work in the browser either:

<!--[if mso]>
    <style>
        .example-class {
            /* Outlook-specific CSS goes here. */
        }
    </style>
<![endif]-->

Are there known browser hacks for Outlook (Outlook.com) in 2022?
