Question

我正在为Outlook开发一个加载项，我按照创建加载项的基本步骤进行操作，但每当我运行（未经编辑的预生成）项目时，我都会收到以下错误：

无法启动此加载项。关闭此对话框以忽略该问题，或单击“重新启动”以重试。

我首先想到这可能与Visual Studio ISS的HTTPS证书有关，但在安装之后（并测试它们在Chrome中的工作情况）。我还更改了徽标，看看它是否有任何效果，但它会一直显示默认图像。

有谁知道我做错了什么？这是我目前的清单：

错误的屏幕截图：

Answer 1

此错误的最可能原因是超时。在Outlook抛出错误之前，您的加载项有5秒钟的时间来执行Office.initialize方法。

通常，当发生这种情况时，这是因为您没有引用<head>中的office.js库，或者在加载DOM之前不执行Office.initialize。

您可以找到有关引用office.js @ Understanding the JavaScript API for Office

的详细信息

Answer 2

在您发布的XML清单文件中，有9次出现~remoteAppUrl。如果您还没有这样做，则应将每个AppDomain替换为代表加载项（Web应用程序）文件部署位置的HTTPS URL。

另外，正如上面评论中提到的 @Slava Ivanov - 我相信每个https://www.test.com值应该是包含协议的URI（例如：{{1}}）。

无法启动加载项
