Question

我正在尝试使用VBA脚本自动将具有特定主题的所有传入电子邮件导出到文本文件，然后我将使用Python脚本进行解析。下面的代码大部分都适用，但会随机跳过一些电子邮件。

我还没有找到任何理由说明为什么会这样，并且它每天都不会跳过来自同一发件人的电子邮件，因此会有所不同。

如果这很重要，我们会在30分钟左右的时间内收到大约20-30封电子邮件。我非常喜欢这方面的帮助。

Private Sub Items_ItemAdd(ByVal Item As Object)
Dim strSubject As String
strSubject = Item.Subject
  If TypeOf Item Is Outlook.MailItem And strSubject Like "VVAnalyze Results" Then
    SaveMailAsFile Item
  End If
End Sub

Private Sub SaveMailAsFile(oMail As Outlook.MailItem)
  Dim dtDate As Date
  Dim sName As String
  Dim sFile As String
  Dim sExt As String

  sPath = "C:\Users\ltvstatus\Desktop\Backup Reports\"
  sExt = ".txt"
  sName = oMail.Subject
  ReplaceCharsForFileName sName, "_"
  dtDate = oMail.ReceivedTime
  sName = Format(dtDate, "yyyymmdd", vbUseSystemDayOfWeek, _
    vbUseSystem) & Format(dtDate, "-hhnnss", _
    vbUseSystemDayOfWeek, vbUseSystem) & "-" & sName & sExt

  oMail.SaveAs sPath & sName, olSaveAsTxt
End Sub

您的代码对我来说没问题，所以我不确定您是否会使用新邮件覆盖已保存的电子邮件，或者在代码正在处理其中并跳过其他邮件时一次收到多封电子邮件...

我已修改您的代码以在您的收件箱中循环，并添加了功能以创建新文件名（如果该文件已存在...）

如果您在1秒内收到10封电子邮件，该功能将创建FileName(1).txt, FileName(2).txt，依此类推......

我还建议您在SaveAs txt ...
