【问题描述】：

我正在尝试删除超过 30 天的主题中包含“发票”的已发送项目。

它适用于超过 30 天的电子邮件，但不对主题应用过滤器。

我目前使用的代码

Sub MoveAgedMail()

    Dim objOutlook As Outlook.Application
    Dim objNamespace As Outlook.NameSpace
    Dim objSourceFolder As Outlook.MAPIFolder
    Dim objDestFolder As Outlook.MAPIFolder
    Dim objVariant As Variant
    Dim lngMovedItems As Long
    Dim intCount As Integer
    Dim Items As Outlook.Items
    Dim Filter As String
    Dim intDateDiff As Integer
    Dim strDestFolder As String
    
    Set objOutlook = Application
    Set objNamespace = objOutlook.GetNamespace("MAPI")
    Set objSourceFolder = objNamespace.GetDefaultFolder(olFolderSentMail)
    
    Set objDestFolder = objNamespace.GetDefaultFolder(olFolderDeletedItems)

    Filter = "[Subject] = '%" & "invoice" & "%' And [SenderEmailAddress] = _
    'abc @hotmail.com'"

    Set Items = objSourceFolder.Items.Restrict(Filter)

    For intCount = objSourceFolder.Items.Count To 1 Step -1
        Set objVariant = objSourceFolder.Items.Item(intCount)
        DoEvents
        If objVariant.Class = olMail Then
            
            intDateDiff = DateDiff("d", objVariant.SentOn, Now)
             
            If intDateDiff > 30 Then

                objVariant.Move objDestFolder
              
                'count the # of items moved
                lngMovedItems = lngMovedItems + 1

            End If
        End If
    Next
    
    MsgBox "Moved " & lngMovedItems & " messages(s)."
    Set objDestFolder = Nothing
End Sub

【解决方案1】：

您必须使用一组受限制的项目，而不是获取新的项目集合，例如：

 For intCount = objSourceFolder.Items.Count To 1 Step -1
   Set objVariant = objSourceFolder.Items.Item(intCount)

应该改写如下：

 For intCount = Items.Count To 1 Step -1
   Set objVariant = Items.Item(intCount)

不要将 Items 用作变量。

Sub MoveAgedMail()

'Dim objOutlook As Outlook.Application

'Dim objNamespace As Outlook.NameSpace
Dim objNamespace As NameSpace

'Dim objSourceFolder As Outlook.MAPIFolder
Dim objSourceFolder As Folder

'Dim objDestFolder As Outlook.MAPIFolder
Dim objDestFolder As Folder

Dim objVariant As Variant
Dim lngMovedItems As Long
Dim intCount As Integer

'Dim Items As Outlook.Items ' Do not use Items as a variable
Dim resItems As Items

Dim Filter As String
Dim intDateDiff As Integer
Dim strDestFolder As String

'Set objOutlook = Application   ' not necessary
'Set objNamespace = objOutlook.GetNamespace("MAPI")
Set objNamespace = GetNamespace("MAPI")

Set objSourceFolder = objNamespace.GetDefaultFolder(olFolderSentMail)
Debug.Print "objSourceFolder.Items.Count: " & objSourceFolder.Items.Count

Set objDestFolder = objNamespace.GetDefaultFolder(olFolderDeletedItems)

' ?
Filter = "[Subject] = '%" & "invoice" & "%' And [SenderEmailAddress] =" 'abc @hotmail.com'"
Debug.Print Filter

Filter = "[Subject] = '%" & "invoice" & "%'"
Debug.Print Filter

Set resItems = objSourceFolder.Items.Restrict(Filter)
Debug.Print "objSourceFolder.Items.Count: " & objSourceFolder.Items.Count
Debug.Print "resItems.Count: " & resItems.Count

'For intCount = objSourceFolder.Items.Count To 1 Step -1
For intCount = resItems.Count To 1 Step -1

    Set objVariant = resItems.Item(intCount)

    DoEvents

    If objVariant.Class = olMail Then

        intDateDiff = DateDiff("d", objVariant.SentOn, Now)

        If intDateDiff > 30 Then

            objVariant.Move objDestFolder

            'count the # of items moved
            lngMovedItems = lngMovedItems + 1

        End If
    End If
Next

MsgBox "Moved " & lngMovedItems & " messages(s)."
Set objDestFolder = Nothing
End Sub
