我正在开发Outlook加载项，它将与共享邮箱一起使用。目前，办公室加载项在代理方案中不可用，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outlook.office365.com的my add-ins上传它。我得到以下错误。
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'...

任何人都知道为用户部署加载项的任何其他方式，甚至可以测试它而无需上传xml文件？
提前致谢。

我今天遇到过同样的问题。我能够通过将SupportsSharedFolders标签移动到DesktopFormFactor标签的开头来解决它。
而不是这个：
...
<DesktopFormFactor>
<!-- Location of the Functions that UI-less buttons can trigger (ExecuteFunction Actions). -->
<FunctionFile resid="functionFile" />
<SupportsSharedFolders>true</SupportsSharedFolders>
<!-- Message Read -->
...
它看起来应该是这样的
...
<DesktopFormFactor>
<SupportsSharedFolders>true</SupportsSharedFolders>
<!-- Location of the Functions that UI-less buttons can trigger (ExecuteFunction Actions). -->
<FunctionFile resid="functionFile" />
<!-- Message Read -->
...
这是样本清单文件，对我有用。

解释@Bubuhubu的答案，并希望帮助其他人解决这个问题。
如果您使用yo生成器初始创建清单，请参阅以下Microsoft如何撰写文章：https://docs.microsoft.com/en-us/outlook/add-ins/addin-tutorial
您会注意到<VersionOverrides>标签是在没有版本号的情况下创建的。此版本的VersionOverrides元素不支持<SupportsSharedFolders>标记，但1.1版本支持。
您可能认为可以简单地将VersionOverrides标记的xmlns和类型标记更改为1.1以获得支持的标记，但显然OfficeApp标记中不支持1.1 VersionOverrides标记。但是，它作为VersionOverrides 1.0标记的子元素受支持。
因此，解决此问题的最简单方法是从yo generatort获取manifest.xml并找到：
<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides" xsi:type="VersionOverridesV1_0">
在它添加之后：
<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides/1.1" xsi:type="VersionOverridesV1_1">
所以它现在看起来像这样：
<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides" xsi:type="VersionOverridesV1_0">
<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides/1.1" xsi:type="VersionOverridesV1_1">
同样，在文档末尾附近，找到：
</VersionOverrides>
并将其更改为：
</VersionOverrides>
</VersionOverrides>
您现在可以使用<SupportsSharedFolders>，例如您的manifest.xml应如下所示：
. . .
<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides" xsi:type="VersionOverridesV1_0">
<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides/1.1" xsi:type="VersionOverridesV1_1">
<Requirements>
<bt:Sets DefaultMinVersion="1.3">
<bt:Set Name="Mailbox" />
</bt:Sets>
</Requirements>
<Hosts>
<Host xsi:type="MailHost">
<DesktopFormFactor>
<SupportsSharedFolders>true</SupportsSharedFolders>
. . .
</VersionOverrides>
</VersionOverrides>
</OfficeApp>
希望这有助于节省一些时间。
顺便说一句，显然当你在Outlook中添加一个插件时，它可能需要60秒才能显示出来。因此，如果您没有立即看到您的图标，请不要首先假设它不起作用（就像我最初那样）。
