Question

我在这个代码中遇到了这个奇怪的问题。我试图在Outlook的所有子文件夹中列出Excel中的所有电子邮件：

我已经搜索并研究了几个星期而没有任何运气。

'Requires reference to Outlook library
Option Explicit

Public Sub ListOutlookFolders()

    Dim olApp As Outlook.Application
    Dim olNamespace As Outlook.Namespace
    Dim olFolder As Outlook.MAPIFolder
    Dim rngOutput As Range
    Dim lngCol As Long
    Dim olItem As Outlook.MailItem

    Dim rng As Excel.Range
    Dim strSheet As String
    Dim strPath As String

    Set rngOutput = ActiveSheet.Range("A1")

    Set olApp = New Outlook.Application
    Set olNamespace = olApp.GetNamespace("MAPI")

    For Each olFolder In olNamespace.Folders
        rngOutput = olFolder.Name
        rngOutput.Offset(0, 1) = olFolder.Description
        Set rngOutput = rngOutput.Offset(1)
        For Each olItem In olFolder.Items
            Set rngOutput = rngOutput.Offset(1)
            With rngOutput
                .Offset(0, 1) = olItem.SenderEmailAddress ' Sender
            End With
        Next

        Set rngOutput = ListFolders(olFolder, 1, rngOutput)
    Next

    Set olFolder = Nothing
    Set olNamespace = Nothing
    Set olApp = Nothing

End Sub

Function ListFolders(MyFolder As Outlook.MAPIFolder, Level As Integer, theOutput As Range) As Range        
    Dim olFolder As Outlook.MAPIFolder
    Dim olItem As Outlook.MailItem
    Dim lngCol As Long

    For Each olFolder In MyFolder.Folders
        theOutput.Offset(0, lngCol) = olFolder.Name
        Set theOutput = theOutput.Offset(1)

        If (olFolder.DefaultItemType = olMailItem) And (Not olFolder.Name = "Slettet post") Then
            For Each olItem In olFolder.Items
                If olItem.Class = olMail Then
                    With theOutput
                        .Offset(0, 1) = olItem.SenderEmailAddress ' Sender
                    End With
                    Set theOutput = theOutput.Offset(1)
                End If
            Next olItem <--- ERROR 13 here
        End If
        If olFolder.Folders.Count > 0 Then
            Set theOutput = ListFolders(olFolder, Level + 1, theOutput)
        End If
    Next olFolder
    Set ListFolders = theOutput.Offset(1)

End Function

代码运行正常10-20项，然后在上述行中给我一个运行时错误13，当我点击调试它告诉我olItem = = Nothing！？ - 当我单步执行时，代码再次运行一段时间。

我试图插入＆＃34; ON ERROR＆＃34;但是我的列表并不包含所有电子邮件。

我是编程VBA的新手，所以请光临我。

提前致谢

我正在向你解释我的代码：）

更改
Dim olItem As Outlook.MailItem
到
Dim olItem As Object

并非所有文件夹项都是mailitems，因此请避免以这种方式标注olItem变量。这个改变在我的机器上运行良好，而最初我遇到了同样的错误

VBA（Excel）for-each循环的运行时错误13
