您好，

由于Outlook中没有可用的内置选项可用于实现目标，我会将您的问题转移到Outlook开发论坛，看看是否可以通过VBA：

Since there is no build-in option available in Outlook can be used to achieve the goal, I'll move your question to the forum for Outlook development to see whether it's possible via VBA:

我们建议适当发布的原因是您将获得最合格的受访者群体以及其他阅读论坛定期可以分享他们的知识或从与我们的互动中学习。感谢您的理解。

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

问候，
