Outlook 2010中VBA项目的数字证书问题。

我开始在Outlook 2010中收到有关我的VBA项目的消息："数字证书存在问题。无法签署VBA项目。签名将被丢弃。"

I started getting this message concerning my VBA project in Outlook 2010: "There was a problem with the digital certificate. The VBA project could not be signed. The signature will be discarded."

今天开始发生，没有明显的原因。

This started happening today, for no apparent reason.

证书尚未过期，是一个我使用以下说明创建：

The certificate has not expired, and is one I created using instructions from:

https://msdn.microsoft.com/en-us/library/bfsktky3%28v=vs.110%29.aspx?f= 255& MSPPError = -2147217396

https://msdn.microsoft.com/en-us/library/bfsktky3%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396

我使用了这个命令：

makecert -r -pe -n" CN = Frank Spafford"  -e 01/01/2053 -eku 1.3.6.1.5.5.7.3.3 -ss My

makecert -r -pe -n "CN=Frank Spafford"  -e 01/01/2053 -eku 1.3.6.1.5.5.7.3.3 -ss My

我尝试创建新证书，并使用新证书签署VBA项目，但是我遇到了同样的错误。

I tried creating a new certificate, and using the new certificate to sign the VBA project, but I encounter the same error.

如何解决这个问题。

问候，

Frank
