Add-In Error: Content is blocked because it isn't signed by a valid security certificate
我正在处理 Outlook 加载项应用程序，发现自己无法在本地 运行 它，在“Office 桌面客户端”中尝试 运行 它时出现以下消息：
“加载项错误内容被阻止，因为它没有由有效的安全证书签名”
当我尝试使用 Chrome 或 Edge 运行 加载项时，我反而在加载项中收到以下消息：
“加载项错误：出了点问题，我们无法启动此加载项。请稍后重试或联系您的系统管理员。”
如果我尝试在 Chrome 或 Edge 上点击“重试”，我会收到以下加载项错误：
“此加载项可能无法正确加载，但您仍然可以尝试启动它。”
当我点击开始时，我得到以下信息：
“位于 https://localhost:44364/AddinClient?et=#/read 的网页可能暂时关闭，或者它可能已永久移动到新网址。”
当尝试通过 chrome 在新选项卡中手动转到此地址时，它设法加载到“此站点注意安全”警告之后的选项卡中
我注意到这个问题的一些常见修复方法，例如在 Internet 选项中将本地主机添加到受信任的站点和安装 office-addin-dev-certs，但是这些选项都没有解决问题（我也尝试删除并重新安装我多次看到的证书）。
还有什么我可以尝试的吗？

“此站点不安全” 解释说该问题是由证书引起的。要解决此问题，您需要在证书存储区内的本地计算机上安装此证书以接受它作为有效证书。
还有一种方法认为您可以尝试使用 http 并检查它是否适合您。
接受警告并允许网站加载不安全的网站，加载后您可以查看证书并存储在您机器的证书存储中。
我不确定加载项的工作原理，但如果您需要，我会尝试并更新您。
我正在处理 Outlook 加载项应用程序，发现自己无法在本地 运行 它，在“Office 桌面客户端”中尝试 运行 它时出现以下消息：
