outlook - 加载项无法启动

Question

我目前正在为 Outlook 开发一个加载项，我遵循了创建加载项的基本步骤，但是每当我运行(未经编辑的预生成的)项目时，我都会收到以下错误:

This add-in could not be started. Close this dialog to ignore the problem or click "Restart" to try again.

我首先认为这可能与 Visual Studio ISS 的 HTTPS 证书有关，但在安装这些证书(并测试它们在 Chrome 中工作)之后。我还更改了 Logo 以查看是否有任何效果，但它一直显示默认图像。

有谁知道我做错了什么？这是我当前的 list :

Answer 1

此错误最可能的原因是超时。在 Outlook 抛出错误之前，您的加载项有 5 秒的时间执行 Office.initialize 方法。

通常发生这种情况是因为您没有在 <head> 中引用 office.js 库或者您在加载 DOM 之前不执行 Office.initialize。

您可以在 Understanding the JavaScript API for Office 中找到有关引用 office.js 的详细信息
