Python win32com演示Outlook Addin.py控制按钮标题不工作

Question

直截了当地说，我尝试使用Python win32com演示outlookAddin.py，它在Outlook 2010中运行良好

我升级到Outlook 2016，从那时起，outlookAddin.py仍在工作，但它在加载项功能区中添加的加载项MSOControl按钮没有标题

谁能帮我理解如何解决这个问题。默认情况下，任何安装win32com的人都可以使用该代码，但我仍在下面提供该代码以供参考

CommandBars已被否决。Office 2010是第一个未将命令栏用于UI的版本。您可以在以下系列文章中阅读有关Fluent UI（也称为Ribbon UI）的更多信息：

• Customizing the 2007 Office Fluent Ribbon for Developers (Part 1 of 3)
• Customizing the 2007 Office Fluent Ribbon for Developers (Part 2 of 3)
• Customizing the 2007 Office Fluent Ribbon for Developers (Part 3 of 3)

定制Office UI的推荐方法是使用Fluent UI。命令栏保留在适当的位置以实现向后兼容性，例如以编程方式执行按钮等。现在不应该依赖命令栏来创建自定义UI
