您好
我有一个用户正在使用我们的MS Office插件for outlook，它允许他们将电子邮件保存到我们的EDRMS系统。
I have a user that is using our MS Office plugin for outlook which allows them to save emails to our EDRMS system.
用户已成功在测试机上安装了该插件，但每当他现在打开Outlook时，他都会收到上述错误。
The user has installed the plugin on a test machine successfully, but whenever he opens outlook now, he gets this error above.
任何想法？
谢谢

推荐答案
看起来您正在尝试将COM对象强制转换为任何托管类型。要了解原因，我建议在代码中添加任何日志记录机制，这样您就可以看到最终用户计算机上发生了什么，并找到确切的代码行。
It looks like you are trying to cast a COM object to any managed type. To understand the cause I'd suggest adding any logging mechanisms to the code, so you could see what happens on an end user machine and find the exact line of code where it happens.
你试着调试代码？
什么行代码准确触发异常？
What line of code exactly fires an exception?
