【问题描述】：

我收到此 Object Required 错误。请参阅下面的代码。我不明白为什么我会得到它。 oitem 变量被声明为一个对象，我在尝试移动它之前对“MailItem”类型进行了测试。请指教。

Sub MoveHarpStatMail()

Dim olapp As Outlook.Application
Dim olappns As Outlook.NameSpace
Dim oitem As Object
Dim ItemsToProcess As Outlook.Items
Dim myFolder As MAPIFolder
Dim sFilter As String
Dim tempMailItem As Outlook.MailItem

On Error GoTo LocalErr

'set outlook objects

Set olapp = New Outlook.Application
Set olappns = olapp.GetNamespace("MAPI")
Set myFolder = olappns.GetDefaultFolder(olFolderInbox)
'Filter or only MailItems received today
sFilter = "[ReceivedTime] >= " & AddQuotes(Format(Date, "ddddd"))
Set ItemsToProcess = Session.GetDefaultFolder(olFolderInbox).Items.Restrict(sFilter)

For Each oitem In ItemsToProcess
 If TypeName(oitem) = "MailItem" Then
   Set tempMailItem = oitem
   If CheckSubject(tempMailItem.Subject) Then
     MoveToArchiveFolder (tempMailItem) '<<<Error 424 Object Required ???
   End If
 End If
Next oitem

ExitProc:
Set olapp = Nothing
Set olappns = Nothing
Set myFolder = Nothing
Set ItemsToProcess = Nothing

...
End Sub

Function CheckSubject(Subject As String) As Boolean

   If (LCase(Trim(Subject)) = LCase(SubjectTitle)) Then
     CheckSubject = True
   Else
     CheckSubject = False
   End If

 End Function

Sub MoveToArchiveFolder(Item As Outlook.MailItem)

  If (ArchiveFolder = Nothing) Then
    MsgBox ("The ArchiveFolder object is not set.")
  End If

  Item.Move (StatsArchiveFolder)

End Sub

标签： vba outlook

【解决方案1】：

去掉括号：

MoveToArchiveFolder tempMailItem

基本上，括号表示评估tempMailItem 的值。 MailItem 的默认属性是电子邮件的主题，因此您的代码将 tempMailItem 的主题传递给您的函数，而不是 MailItem 本身。

这是一个有趣的Daily Dose 帖子，说明了原因。请务必阅读 Rick Rothstein 的评论。
