【问题描述】：
我正在开发适用于共享邮箱的 Outlook 插件。
目前，Office 插件在委托方案中不可用，但 MS 已发布支持这些方案的预览版本。
https://docs.microsoft.com/en-us/office/dev/add-ins/reference/manifest/supportssharedfolders
我的问题是因为 manifest.xml 有预览元素；我无法在my add-ins 下的outlook.office365.com 上传它。我收到以下错误。
This app can't be installed. The manifest file doesn't conform to the schema definition. The element 'DesktopFormFactor' in namespace 'http://schemas.microsoft.com/office/mailappversionoverrides/1.1' has invalid child element 'SupportsSharedFolders' in namespace 'http://schemas.microsoft.com/office/mailappversionoverrides/1.1'. List of possible elements expected: 'ExtensionPoint' in namespace 'http://schemas.microsoft.com/office/mailappversionoverrides/1.1'... The element 'DesktopFormFactor' in namespace 'http://schemas.microsoft.com/office/mailappversionoverrides/1.1' has invalid child element 'SupportsSharedFolders' in namespace 'http://schemas.microsoft.com/office/mailappversionoverrides/1.1'.

任何人都知道任何其他方式来为用户部署外接程序，甚至在不上传 xml 文件的情况下对其进行测试？
提前致谢。
我的 manifest.xml 文件的副本在这里。
