Outlook深色模式下邮件页脚优化失效问题求助

问题说明 #

我无法优化Outlook深色模式下邮件页脚的显示效果，浅色模式与深色模式的显示存在明显差异。

当前页脚核心代码 #

<td style="-webkit-text-size-adjust: 100%; -ms-text-size-adjust: 100%; mso-table-lspace: 0pt; mso-table-rspace: 0pt; padding: 20px; background-color: #000; mso-color-alt: auto; font-size: 15px;" width="100%" valign="top" height="100%" bgcolor="#000" align="center"> 
    <table role="presentation" style="-webkit-text-size-adjust: 100%; -ms-text-size-adjust: 100%; mso-table-lspace: 0pt; mso-table-rspace: 0pt; border-collapse: collapse!important;" cellspacing="0" cellpadding="0" border="0" align="center"> 
        <tbody> 

页脚图标代码示例 #

<tr> 
    <td style="-webkit-text-size-adjust: 100%; -ms-text-size-adjust: 100%; mso-table-lspace: 0pt; mso-table-rspace: 0pt;" width="60" align="center">
                    <a style="-webkit-text-size-adjust: 100%; -ms-text-size-adjust: 100%; color: #ffffff; text-decoration: none; display: block;" href="#" target="_blank" _label="Footer: facebook" data-nl-type="externalLink" data-nl-lnkep-perso-attr-href="https://www.facebook.com/"> <img src="http://.png" alt="facebook logo" style="-ms-interpolation-mode: bicubic; border: 0px; height: auto; line-height: 100%; outline: none; text-decoration: none; width: 33px;" width="33" /></a>
    </td> 

已尝试但无效的解决方案代码 #

<meta name="color-scheme" content="light dark">
<meta name="supported-color-schemes" content="light dark">

<style>
@media (prefers-color-scheme: dark ) {
  .footer { background-color: #000000 !important; }
  p { color: #ffffff !important; }
}
</style>
