如何使用os.remove()删除所有电子邮件文件？通过电子邮件发送到TFS票证
我们目前使用TFS作为支持票证的票证系统。我编写了下面的代码，以便用户可以将电子邮件转储到文件夹中，然后访问网页以提交表单，创建TFS支持票证并将其分配给用户。目标是在提交表单并创建支持票证后，将电子邮件从文件夹中删除。
我遇到的问题是，当我在创建TFS支持票证后尝试删除电子邮件时，它会删除一些文件，但随后会卡在最后一个文件上，并显示以下错误消息。
“由于另一个进程正在使用该文件，因此进程无法访问该文件：'C:\Users\b4bw3\Documents\Python\simple-salesforce\Email\Delete_Me1.msg'”：PermissionError: WinError 32
如果我删除创建TFS票证的代码部分，那么它将重命名电子邮件，并在按预期完成后将其删除。似乎是TFS挂断了。我被难住了，需要帮助。
有什么想法吗？顺便说一句，这是我第一次尝试Python，所以要温文尔雅。:)

我确实尝试在e2tfs()方法的底部添加close()，但收到以下错误：
Python脚本中出现问题。下面是导致错误的函数调用序列，按照它们发生的顺序。

这似乎是msg-提取器的当前错误。我在下面找到了详细解释的链接。
https://github.com/mattgwwalker/msg-extractor/issues/85?_pjax=%23js-repo-pjax-container
我将下面的代码行添加到我的方法的末尾，它的效果很不错。
