首先感谢 AMissico - 我也会查看您提供的描述和链接。以下代码对我有用(但按钮控件和其他控件的布局已损坏-但 WFP 有效,因此我将使用 wpf)。我必须重构代码,但它是我的工作版本......
在为我稍微调整了一下之后,我终于发现这个例子有效:http:

此方法设置 Web 视图:

{
MSOutlook.MAPIFolder root = Folder.GetRootFolder(Application.Session);
MSOutlook.MAPIFolder webViewFolder = Folder.CreateFolder(root, Properties.Resources.WebViewFolderName);
webViewFolder.WebViewURL = FolderHomePage.RegisterType(typeof(WebViewControl));
webViewFolder.WebViewOn = true;
