我为Microsoft Teams创建了一个主页应用程序，该应用程序通过遵循文章Teams app with SharePoint在个人选项卡中呈现SharePoint通信网站(SharePoint(。当我在同一租户的Teams桌面上安装该应用程序时，它运行良好。
在另一个租户(fabrikam.sharepoint(中安装应用程序时，如果用户作为访客添加到拥有sharepoint网站(contoso.sharepoint(的租户，则不会在Teams桌面中加载网站内容。在浏览器选项卡中访问时，一旦我在新选项卡中手动打开SharePoint网站，应用程序就会开始工作。
我正在为应用程序使用的清单：

您试图在概念上做的事情基本上与新的"Viva Connections"；微软的能力，所以你应该考虑走这条路，因为它提供了你正在做的事情以及更多。我刚刚在博客上写了关于这件事的背景，并链接到相关的微软内容，所以看看https://hilton.giesenow.com/2021-03-31-understanding-viva-connections-app-package
不过，就你遇到的实际问题而言，我认为你无法在桌面上实现这一点，因为Teams应用程序是如何管理当前登录上下文的，但也许其他人会有另一个解决方案。
目前团队不支持跨租户查看SharePoint页面/网站的选项。访客用户也不受支持。
