发布使用 Outlook 预览元素的 Outlook 加载项 - SupportsSharedFolders
Publishing Outlook add-in which uses Outlook preview element - SupportsSharedFolders
我正在开发可与共享邮箱一起使用的 Outlook 加载项。
目前，office 插件在委托场景中不可用，但 MS 已经发布了支持这些场景的预览版本。
https://docs.microsoft.com/en-us/office/dev/add-ins/reference/manifest/supportssharedfolders
我的问题是 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'.

任何人都知道为用户部署加载项甚至测试它而无需上传 xml 文件的任何其他方法吗？
提前致谢。

我今天遇到了同样的问题。我能够通过移动来解决它
SupportsSharedFolders 标记到 DesktopFormFactor 标记的开头。
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 -->
...
这是对我有用的示例清单文件。

解释@Bubuhubu 的回答，希望能帮助遇到此问题的其他人。
如果您使用 yo 生成器最初创建您的清单，如以下 Microsoft 如何文章中所述：
https://docs.microsoft.com/en-us/outlook/add-ins/addin-tutorial
您会注意到创建的 <VersionOverrides> 标签没有版本号。此版本的 VersionOverrides 元素不支持 <SupportsSharedFolders> 标记，但 1.1 版本支持。
您可能认为您可以简单地将 VersionOverrides 标记的 xmlns 和类型标记更改为 1.1 以获得标记支持，但显然 OfficeApp 标记不支持 1.1 VersionOverrides 标记。但是，支持它作为 VersionOverrides 1.0 标记的子元素。
因此，解决此问题的最简单方法是从生成器中获取 manifest.xml 并找到：
<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides" xsi:type="VersionOverridesV1_0">
紧接着添加：
<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，当您在 Outlook 中添加插件时，它最多可能需要 60 秒才能显示出来。因此，如果您没有立即看到您的图标，请不要一开始就假设它不起作用（就像我最初所做的那样）。

解释@Bubuhubu 的回答，希望能帮助遇到此问题的其他人。
如果您使用 yo 生成器最初创建您的清单，如以下 Microsoft 如何文章中所述： https://docs.microsoft.com/en-us/outlook/add-ins/addin-tutorial
您会注意到创建的 <VersionOverrides> 标签没有版本号。此版本的 VersionOverrides 元素不支持 <SupportsSharedFolders> 标记，但 1.1 版本支持。
您可能认为您可以简单地将 VersionOverrides 标记的 xmlns 和类型标记更改为 1.1 以获得标记支持，但显然 OfficeApp 标记不支持 1.1 VersionOverrides 标记。但是，支持它作为 VersionOverrides 1.0 标记的子元素。
因此，解决此问题的最简单方法是从生成器中获取 manifest.xml 并找到：
<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides" xsi:type="VersionOverridesV1_0">
紧接着添加：
<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，当您在 Outlook 中添加插件时，它最多可能需要 60 秒才能显示出来。因此，如果您没有立即看到您的图标，请不要一开始就假设它不起作用（就像我最初所做的那样）。
