Outlook Add In登录页和重定向在Outlook中有效，但在Outlook Web中无效

Question

我做了一个Office Add，通过Razor页面.Net Core应用程序获取页面。我正在使用AspNetCore.Identity进行身份验证。它具有此URL（“ https://localhost:44311/Identity/Account/Login”）作为默认登录页面。在我的Outlook客户端中，您可以按预期工作，但是在Outlook Web上不会加载“添加ir”。

我尝试加载匿名页面（无身份验证），并且在Web和本地客户端上均可使用。

我希望：登录页面会加载到Outlook Web中。

实际结果：
