【中文标题】我可以遍历文件夹（包括子文件夹）中的所有 Outlook 电子邮件吗？

【英文标题】：Can I iterate through all Outlook emails in a folder including sub-folders?

【问题描述】：

我有一个文件夹，其中包含许多电子邮件和子文件夹。这些子文件夹中有更多电子邮件。

我想编写一些 VBA，它将遍历某个文件夹中的所有电子邮件，包括任何子文件夹中的电子邮件。这个想法是从每封电子邮件中提取SenderEmailAddress 和SenderName 并对其进行处理。

我尝试将文件夹导出为仅包含这两个字段的 CSV，虽然这可行，但它不支持导出子文件夹中保存的电子邮件。因此需要编写一些 VBA。

在我重新发明***之前，是否有人有任何代码 sn-ps 或网站链接，给定文件夹名称，显示如何为该文件夹中的每封电子邮件获取 MailItem 对象和 后续子文件夹？

【参考方案1】：

类似这样的...

 Private Sub processFolder(ByVal oParent As Outlook.MAPIFolder)

        Dim oFolder As Outlook.MAPIFolder
        Dim oMail As Outlook.MailItem

        For Each oMail In oParent.Items

        'Get your data here ...

        Next

        If (oParent.Folders.Count > 0) Then
            For Each oFolder In oParent.Folders
                processFolder oFolder
            Next
        End If
End Sub

【参考方案2】：

这有很多你感兴趣的很棒的代码。在 Outlook/VBA 中将其作为宏运行。

Const MACRO_NAME = "OST2XLS"

Dim excApp As Object, _
    excWkb As Object, _
    excWks As Object, _
    intVersion As Integer, _
    intMessages As Integer, _
    lngRow As Long

Sub ExportMessagesToExcel()
    Dim strFilename As String, olkSto As Outlook.Store
    strFilename = InputBox("Enter a filename (including path) to save the exported messages to.", MACRO_NAME)
    If strFilename <> "" Then
        intMessages = 0
        intVersion = GetOutlookVersion()
        Set excApp = CreateObject("Excel.Application")
        Set excWkb = excApp.Workbooks.Add
        For Each olkSto In Session.Stores
            Set excWks = excWkb.Worksheets.Add()
            excWks.Name = "Output1"
            'Write Excel Column Headers
            With excWks
                .Cells(1, 1) = "Folder"
                .Cells(1, 2) = "Sender"
                .Cells(1, 3) = "Received"
                .Cells(1, 4) = "Sent To"
                .Cells(1, 5) = "Subject"
