Arrays Outlook中删除重复电子邮件的宏- Public Sub RemDups（） 将t作为项目_ i作为整数_ arr作为集合_ f作为文件夹_ 父文件夹_ 目标为文件夹_ miLast作为邮件项目_ mi作为邮件项 设置parent=Application.GetNamespace（“MAPI”）.PickFolder Set target=Application.GetNamespace（“MAPI”）.PickFolder 对于父文件夹中的每个f 设置t=f项 t、 排序“[主题]” i=1 集miLast=t（i） Set arr=新集合 当我数的时候 i=i+1 如果TypeName（t（i））=“MailItem”，则 设置mi=t（i） 如果miLast.Subject=mi.Subject，miLast.Body=mi.Body_ 然后miLast.ReceivedTime=mi.ReceivedTime A.添加mi 其他的 设置miLast=mi 如果结束 如果结束 温德 对于arr中的每个mi 移动目标 下一个mi 下一个f 端接头

Set miLast=t（i）给出“运行时错误'440'数组索引超出范围”

请提供帮助

这是一个在web上创建的修改版本（）

这段代码允许选择一个文件夹来搜索和删除重复的项目

Public Sub RemDups()

Dim t As Items, _
    i As Integer, _
    arr As Collection, _
    f As Folder, _
    parent As Folder, _
    target As Folder, _
    miLast As MailItem, _
    mi As MailItem

Set parent = Application.GetNamespace("MAPI").PickFolder
Set target = Application.GetNamespace("MAPI").PickFolder


For Each f In parent.Folders
    Set t = f.Items
    t.Sort "[Subject]"
    i = 1
    Set miLast = t(i)
    Set arr = New Collection
    While i < t.Count
        i = i + 1
        If TypeName(t(i)) = "MailItem" Then
            Set mi = t(i)
            If miLast.Subject = mi.Subject And miLast.Body = mi.Body _
            And miLast.ReceivedTime = mi.ReceivedTime Then
                arr.Add mi
            Else
                Set miLast = mi
            End If
        End If
    Wend
    For Each mi In arr
        mi.Move target
    Next mi
Next f

End Sub

更好的版本是在递归模式下在其他文件夹中查找重复的电子邮件。

当您得到该错误时，

f.Items.Count

的值是多少？当我编译代码时，我得到的只是“运行时错误”。它不提供任何计数使用t.Item（I）方法通过集合中的索引获取项目。
