UiPath直接操作邮件模板，我还没解决email body读取的问题，selector取不到ID,有大神懂的话，请指导一下。
所以，用Powershell处理的邮件模板问题，调试通过，代码在后面，现在就调试中遇到的坑写一下：
1.Uipath调用Powershell 参数名称一定要一摸一样；
2.如果Uipath调用PS时报错，报错的内容可能跟实际的错误有区别，代码不长的话，我都是用最笨的方法，一句一句的写出来调试，像今天这个邮件处理模板的，第一条记录$olApp = New-Object -ComObject Outlook.Application;就会报错，这就特别奇葩，还有千万年不出错的[System.GC]::Collect()释放，也会出错，究其原因，都是这些语句的错误。肯定是上面 或者附近的语句有错误。
ps：$olApp = New-Object -ComObject Outlook.Application;报错的原因是 邮件没关闭，我开着自己的工作邮件在开发的，关闭有就解决了。
3.在Uipath 与Ps联合单元测试通过后，放入项目中，又是报错不管，调试最后，发现传入的参数，字符串前面有空格，除去后运行正常。踩坑的同学注意了。
