vba - 如何在我的辅助邮件帐户中获取有关新邮件的信息？

Outlook中有几个邮件帐户。

有一个代码可以生成一个消息框，其中包含主邮箱中新邮件的属性。它适用于我的主要邮件帐户。

Option Explicit
Private WithEvents inboxItems As Outlook.Items
Private Sub Application_Startup()
  Dim outlookApp As Outlook.Application
  Dim objectNS As Outlook.NameSpace

  Set outlookApp = Outlook.Application
  Set objectNS = outlookApp.GetNamespace("MAPI")


  Set inboxItems = objectNS.GetDefaultFolder(olFolderInbox).Items
End Sub
Private Sub inboxItems_ItemAdd(ByVal Item As Object)
On Error GoTo ErrorHandler
Dim Msg As Outlook.MailItem
Dim MessageInfo
Dim Result
If TypeName(Item) = "MailItem" Then
    MessageInfo = "" & _
        "Sender : " & Item.SenderEmailAddress & vbCrLf & _
        "Sent : " & Item.SentOn & vbCrLf & _
        "Received : " & Item.ReceivedTime & vbCrLf & _
        "Subject : " & Item.Subject & vbCrLf & _
        "Size : " & Item.Size & vbCrLf & _
        "Message Body : " & vbCrLf & Item.Body
    Result = MsgBox(MessageInfo, vbOKOnly, "New Message Received")
End If
ExitNewItem:
    Exit Sub
ErrorHandler:
    MsgBox Err.Number & " - " & Err.Description
    Resume ExitNewItem
End Sub

弹出消息如下所示：

还有另一个邮箱“ Specification Estimation RU41”。我的任务是为该邮箱收到新的传入邮件相同的弹出消息。我换了线

Set inboxItems = objectNS.GetDefaultFolder(olFolderInbox).Items

与

Set inboxItems = objectNS.Folders("Specification Estimation RU41") _
                    .Folders("Inbox").Items

这样整个代码看起来像这样：

Option Explicit
Private WithEvents inboxItems As Outlook.Items
Private Sub Application_Startup()
  Dim outlookApp As Outlook.Application
  Dim objectNS As Outlook.NameSpace

  Set outlookApp = Outlook.Application
  Set objectNS = outlookApp.GetNamespace("MAPI")
 Set inboxItems = objectNS.Folders("Specification Estimation RU41") _
                    .Folders("Inbox").Items


End Sub
Private Sub inboxItems_ItemAdd(ByVal Item As Object)
On Error GoTo ErrorHandler
Dim Msg As Outlook.MailItem
Dim MessageInfo
Dim Result
If TypeName(Item) = "MailItem" Then
    MessageInfo = "" & _
        "Sender : " & Item.SenderEmailAddress & vbCrLf & _
        "Sent : " & Item.SentOn & vbCrLf & _
        "Received : " & Item.ReceivedTime & vbCrLf & _
        "Subject : " & Item.Subject & vbCrLf & _
        "Size : " & Item.Size & vbCrLf & _
        "Message Body : " & vbCrLf & Item.Body
    Result = MsgBox(MessageInfo, vbOKOnly, "New Message Received")
End If
ExitNewItem:
    Exit Sub
ErrorHandler:
    MsgBox Err.Number & " - " & Err.Description
    Resume ExitNewItem
End Sub

但这是行不通的。没有错误消息，但是对新邮件没有反应。

我该如何运作？
