使用Excel VBA将收到的电子邮件每日记录从Outlook导出到文件

因此，我发现人们可以在Outlook中的一个文件夹中导出他们每天收到的电子邮件数量。问题是我需要对数百个文件夹执行此操作，因此我要尝试使其查看主文件夹中的所有子文件夹。如果我在一个文件夹中查找，并将其很好地导出，那么这种方法很好用。我想我已经达到了我的能力极限。我是朝着正确的方向前进，还是朝着效率低下的方向前进

非常接近一个解决方案现在只是崩溃，这可能是因为我有数以万计的电子邮件

在开发过程中，在出错时删除转到，以便更容易地查看出错的行

在处理所有子文件夹之前，您无需关注当前错误

试试这个：

Private Sub LoopFolders_Test()

    'Application Variables
    Dim olApp As Outlook.Application
    Dim objNS As Outlook.Namespace
    Dim myolItems As Folder

    Dim Start As Date
    Dim EndTime As Date

    Set olApp = Outlook.Application
    Set objNS = olApp.GetNamespace("MAPI")
    'Set myOlItems = objNS.GetDefaultFolder(olFolderInbox)
    Set myolItems = objNS.PickFolder

    If myolItems Is Nothing Then GoTo exitRoutine

    Start = Now
    Debug.Print "Start: " & Start
    Debug.Print "Startfolder Name: " & myolItems.Name

    'Disable Screen Updating
    'Application.ScreenUpdating = False

    LoopFolders myolItems.Folders

    ' Finalize Excel display here

exitRoutine:
    Set olApp = Nothing
    Set objNS = Nothing
    Set myolItems = Nothing  

    'Enable Screen Updating
    'Application.ScreenUpdating = True

    EndTime = Now
    Debug.Print "End  : " & EndTime
    Debug.Print Format((EndTime - Start) * 86400, "#,##0.0") & " seconds"

End Sub

Private Sub LoopFolders(olFolders As Folders)

  Dim F As Folder

  For Each F In olFolders
    DoEvents    
    Debug.Print "Subfolder Name: " & F.Name ' Code has not crashed
    ' Count mail here
    LoopFolders F.Folders
  Next

End Sub

您的不匹配项在哪里？修复了不匹配项，将item设置为Object而不是MailItem。不匹配项设置为item=myOlItems.Itemsi。现在我不知道代码是崩溃了还是要花很长时间，因为我有21k封电子邮件要处理。
