我有一个类似的 mailto 链接，<a href="mailto:a&[email protected]" > 它可以在 html 上正确显示，但是当我们单击该链接时，Outlook 只在 to 地址中显示一个。有没有人遇到过同样的问题，请提出建议。

Percent encodingthe string is required for IE and I assume will work across browsers. From this MSDN document:
IE 需要对字符串进行百分比编码，我认为可以跨浏览器工作。从 这个 MSDN 文档：
Windows Internet Explorer 7 and later. You must percent-encode all URL-reserved characters within a mailto: address. For example, the number sign (#) is used as a fragment identifier in URLs. When processing an address such as some#[email protected], Internet Explorer copies only the portion up to the number sign into the mail client; the fragment portion including the number sign is ignored. This behavior is by design.
Windows Internet Explorer 7 及更高版本。您必须对 mailto: 地址中的所有 URL 保留字符进行百分比编码。例如，数字符号 (#) 在 URL 中用作片段标识符。在处理诸如 some#[email protected] 之类的地址时，Internet Explorer 仅将数字符号之前的部分复制到邮件客户端；包含数字符号的片段部分将被忽略。此行为是设计使然。
So you need
所以你需要
<a href="mailto:a%26b_admin%40xyz.com">
As said, I expect a percent encoded address will work in all browsers, but I don't know for sure. I can confirm it works with Chrome and Thunderbird.
如上所述，我希望百分比编码的地址适用于所有浏览器，但我不确定。我可以确认它适用于 Chrome 和 Thunderbird。
