我们目前使用 TFS 作为支持工单的工单系统。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并创建 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从文件夹中删除电子邮件。
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，但随后卡在最后一个文件上并显示以下错误消息。
"权限错误： [WinError 32] 进程无法访问该文件，因为它正被另一个进程使用："C：\Users\b4bw3\Documents\Python\simple-salesforce\Email\Delete_Me1.msg'">
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。挂断似乎是TFS的。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，所以要温柔。:)

我确实尝试在 e2tfs(( 方法的底部添加 close((，但我收到以下错误：

这似乎是味精提取器的当前错误。我找到了下面的链接，详细解释了。

我在方法的末尾添加了以下代码行，它就像一个魅力。
msg.close()
