Python win32com 演示 outlookaddin.py 控制按钮标题不起作用

Question

开门见山，我尝试使用 Python win32com 演示 outlookAddin.py，它在 Outlook 2010 上运行良好。

我升级到 Outlook 2016，此后 outlookAddin.py 仍在工作，但是它在 Add-ins 功能区中添加的插件 msoControlButton 没有标题。

任何人都可以帮助我了解如何解决这个问题。默认情况下，任何安装了 win32com 的人都可以使用该代码，但我仍然在下面提供它以供参考。

gencache.EnsureModule('{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52}', 0, 2, 1, bForDemand=True) # Office 9

CommandBars 已弃用。 Office 2010 是第一个不使用命令栏的版本 UI。您可以在以下系列文章中阅读有关 Fluent UI（又名 Ribbon UI）的更多信息：

自定义 Office UI 的推荐方法是使用 Fluent UI。命令栏保持原位以实现向后兼容性，例如以编程方式执行按钮等。您现在不应该依赖命令栏来创建自定义 UI。
