我正尝试从Java邮件（充气城堡1.51）发送S/MIME签名和加密邮件给我自己，以将其发送给我的Outlook。使用Outlook 2010查看S/MIME邮件
我能够发送正常的邮件，但接收是一个问题，因为Outlook不想打开邮件。以下是我尝试打开时出现的错误：
无法打开此项目。您的数字身份证名称不能被底层安全系统找到。
使用p7m查看器可以看到相同的邮件（保存到本地文件的eml格式），表明P12证书已正确安装在我的笔记本电脑上。我在我的Java邮件代码中安装了与我在Keystore中使用的P12文件相同的文件。
我做错了什么？ Outlook的问题是否结束？我正在使用Office 365，并希望添加p7m Viewer也无法打开从Outlook WebMail下载的smime.p7m。我收到的错误是：
该文件已损坏;签名信息可能会丢失。
下面是我用来加密/发送邮件的Java代码。

PLZ帮助！

另外，您也可以直接双击.p12文件开始导入过程 – Jeff 2014-11-13 18:09:49
感谢杰夫。是的，试过但没有工作！我收到了同样的错误。 – Sumit 2014-11-17 07:47:49
我在Outlook中遇到了一个问题，在其中一个电子邮件标题中出现了无意中的换行符。删除换行突然让Outlook开心，我可以再次查看消息。其他客户更容忍畸形标题。难道你的电子邮件在某个地方有一个不好的标题？ – Jeff 2014-12-02 16:53:43
