有没有办法判断电子邮件中的活动/焦点文本字段是否在 VBA 中的 Outlook 中更改？ 即用户从“到”点击到“主题”

如何解决有没有办法判断电子邮件中的活动/焦点文本字段是否在 VBA 中的 Outlook 中更改？ 即用户从“到”点击到“主题”

当用户将活动字段从新电子邮件的“收件人”字段更改为电子邮件的正文时，我正在尝试执行例行程序。目的是能够使用收件人姓名自动填充问候语。

我让它立即运行以获取全部基于资源管理器选择更改的回复或回复，但我无法找到或找出正确的条件语句让脚本等到“To”字段之后点击离开。

有什么想法可以在 VBA 中实现吗？如果是这样怎么办？如果没有其他建议？

提前致谢！
