如何使用EWS PowerShell发送含自定义投票选项的邮件

我来帮你搞定这个投票选项的问题——你之前尝试修改Verb Stream没成功，是因为投票选项的Hex结构需要对应调整，尤其是$ApproveOption、$RejectOption和$VoteOptionExtras这几个核心部分。下面是修改后的完整代码和分步解释：

关键修改点说明 #

1. 替换投票选项的Hex定义：
   • 原来的$ApproveOption和$RejectOption被替换成$YesOption和$NoOption，每个选项的Hex结构里包含了选项的文本（比如03596573对应ASCII的"Yes"），以及MAPI类型标记。
2. 更新$VoteOptionExtras：
   • 这个变量里存储的是投票选项的Unicode编码文本（比如03590065007300对应Unicode的"Yes"），确保邮件客户端能正确显示投票按钮的文本。
3. 拼接VerbStream时替换选项：
   • 在最终的$VerbValue拼接中，用新的$YesOption和$NoOption替换原来的$ApproveOption和$RejectOption。

如何自定义其他投票选项 #

如果想要改成比如“同意/不同意”或者“Accept/Decline”，只需要：

1. 将你要的投票文本转成ASCII Hex（用于选项变量，开头要加文本长度的Hex值）和Unicode Hex（用于$VoteOptionExtras）。
   • 举个例子，要添加“Accept”选项：
     • ASCII Hex是06416363657074（"Accept"长度是6，所以开头是06）
     • Unicode Hex是004100630063006500700074
2. 复制$YesOption的结构，替换其中的文本Hex部分，生成新的选项变量。
3. 在$VoteOptionExtras末尾添加对应的Unicode Hex文本。

验证效果 #

发送邮件后，收件人在Outlook或其他支持EWS投票的客户端中，会看到你自定义的投票按钮（比如Yes/No），而不是默认的Approve/Reject。
