如何在 Outlook Web App (OWA)、Outlook 2016 Mac 和 Windows 中的 Outlook 加载项中显示垂直窗格

我正在开发一个针对 OWA、Outlook 2016 for Mac & Windows 的 Outlook 插件。我的要求是显示加载项垂直位于右侧在阅读和撰写邮件时。对于撰写，它默认显示为所需的，但对于阅读，它是水平显示的，我想垂直显示。简而言之，我喜欢展示我的加载项与 Evernote 加载项完全相同正在显示。

我们将非常感谢您的帮助。以下 OWA 中 Evernote 的屏幕截图是我想要显示的内容，包括图标位置（以红色包围）。

提前致谢。

我使用 YEOMAN Office Generator 制作了这样的垂直插件。使用此链接供参考。yeoman-office-generator 的 GitHub 链接。并在您的manifest.xml文件中进行如下更改：
