推荐答案

这个问题是由一个叫做 Extension Hardening 的特性引起的，你可以找到更多关于它的信息 这里

This problem results from a feature called Extension Hardening, and you can find more information about it here

我在我的项目中经常遇到这个问题，就像 Jon 所说的，关闭扩展强化是每个客户端用户都必须完成的事情.

I've run into this problem a lot in my projects, and like Jon said, turning off Extension Hardening is something that will have to be done by each client side user.

不幸的是，上面的链接还指出，至少在 Office 14 之前，不会对此代码进行预期的更改.

Unfortunately, the link above also states that there are no expected changes to this code until at least Office 14.
